Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high-salinity, or poor air-circulation environments.There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required.

Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by forming more iron oxide; and, because of the greater volume of the iron oxide, this tends to flake and fall away. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal's internal structure.Passivation occurs only if the proportion of chromium is high enough and oxygen is present.

[Site] Robot repeat positioning error is only 0.05 mm
Guangzhou CNC Equipment Co., Ltd. is currently the largest R&D and production base of CNC machine tools in China. Its annual output and sales CNC system ranks first in the country for 12 consecutive years, accounting for 50% of the domestic market share of similar products.
In 2006, the company was involved in the field of robotics. It is not only one of the drafting units of the national robot standard, but also the research of industrial robots and special motors in the national 863 project. It is one of the few companies with independent intellectual property rights in research and development of robots. .
Industrial robots are multi-joint robots or multi-degree-of-freedom robots for the industrial sector. They can be operated according to pre-programmed procedures and automatically perform their work with their own power and control.
Yesterday, the Luoyang Evening News reporter saw the wonderful performances of loading and unloading robots, palletizing robots, welding robots, de-hairing robots, handling robots, parallel robots, etc.
Among them, the welding robot can not only adjust the welding posture arbitrarily, but also adapt to the welding of various forms and structures, and its repeated positioning error is only 0.05 mm, far exceeding the human vision positioning; the parallel robot grasping the can bottle cap is not only accurate, And the speed is very fast, up to 120 times per minute.
A staff member in charge of the live demonstration told the Luoyang Evening News reporter that the main advantage of the robot is that it is hard-working and standardized, and can work continuously for a long time. Those dirty, tired, bitter or simple and dull repetitive work is most suitable for them.
A robot can generally "live" for 10 years. How much does it cost to "employ" such a robot? The staff said that before the Chinese, most of the key components of robots rely on imports, the price is high, but in recent years, companies like Guangzhou CNC have gradually acquired their own intellectual property rights, and the price of robots has dropped significantly. In Guangzhou CNC Company, the price of these robots is generally more than 100,000 yuan or more than 200,000 yuan, and some are less than 100,000 yuan, which is equivalent to only one employee's salary for two years.
[Prospect] It is estimated that in the next five years, Luoyang will have 3,000 industrial robots "on the job"
Ma Tao, general manager of Yituo (Luoyang) Kaichuang Equipment Technology Co., Ltd. said that in recent years, as the cost of labor for enterprises has been rising, more and more companies have set their sights on robots.
Some experts predict that by 2015, China's robot market demand will reach 35,000 units, accounting for 16.9% of the global total, becoming the largest robot market. Therefore, hand in hand with Guangzhou CNC Company to jointly create “Chinese Robotâ€, not only can improve labor efficiency, save production costs, but also drive the transformation and upgrading of traditional industries in the city and foster new economic growth points.
It is estimated that in the next five years, Luoyang will have 3,000 industrial robots in the production posts in different fields, and the demand for one trailer is more than 500, and it is expected to reach 1,000.
For the cooperation with Guangzhou CNC Company, the person in charge of Yituo Group said that as a holding subsidiary of Yituo Group, Yituo (Luoyang) Kaichuang Equipment Technology Co., Ltd. was originally a production preparation base and a new product trial base. Process research and development, process equipment design, manufacturing, installation, commissioning and delivery capabilities and R & D team, this time with the Guangzhou CNC company, participate in the "Chinese robot" manufacturing, will greatly enhance the company's entire line of automation, expand the field of robot applications Finally, we will provide competitive robot production lines for users in the central and western regions of China.

Oxidation
High oxidation resistance in air at ambient temperature is normally achieved with additions of a minimum of 13% (by weight) chromium, and up to 26% is used for harsh environments.[4] The chromium forms a passivation layer of chromium(III) oxide (Cr2O3) when exposed to oxygen. The layer is too thin to be visible, and the metal remains lustrous and smooth. The layer is impervious to water and air, protecting the metal beneath, and this layer quickly reforms when the surface is scratched. This phenomenon is called passivation and is seen in other metals, such as aluminium and titanium. Corrosion resistance can be adversely affected if the component is used in a non-oxygenated environment, a typical example being underwater keel bolts buried in timber.
When stainless steel parts such as nuts and bolts are forced together, the oxide layer can be scraped off, allowing the parts to weld together. When forcibly disassembled, the welded material may be torn and pitted, an effect known as galling. This destructive galling can be avoided by the use of dissimilar materials for the parts forced together, for example bronze and stainless steel, or even different types of stainless steels (martensitic against austenitic). However, two different alloys electrically connected in a humid environment may act as a voltaic pile and corrode faster. Nitronic alloys made by selective alloying with manganese and nitrogen may have a reduced tendency to gall. Additionally, threaded joints may be lubricated to prevent galling. Low-temperature carburizing is another option that virtually eliminates galling and allows the use of similar materials without the risk of corrosion and the need for lubrication.
Stainless steel is generally highly resistant to attack from acids, but this quality depends on the kind and concentration of the acid, the surrounding temperature, and the type of steel. Type 904 is resistant to sulfuric acid at room temperature, even in high concentrations; type 316 and 317 are resistant below 10%, and 304 should not be used in the presence of sulfuric acid at any concentration. All types of stainless steel resist attack from phosphoric acid, 316 and 317 more so than 304; types 304L and 430 have been successfully used with nitric acid. Hydrochloric acid will damage any kind of stainless steel, and should be avoided.
3000 industrial robots are expected to be "on the job" in Luo
Yesterday, Yituo (Luoyang) Kaichuang Equipment Technology Co., Ltd. and the National Robot Standards Drafting Member--Guangzhou CNC Equipment Co., Ltd. officially signed a strategic cooperation agreement, and Guangzhou CNC Company entrusted the creation of a technology company as the total promotion of robots in the central and western regions of China. Acting, the pioneering technology company provides processing services and production line development services for the key mechanical components of Guangzhou CNC company. This indicates that Yituo Group will be involved in the field of robot manufacturing. It is expected that in the next five years, the city is expected to promote the use of 3,000 industrial robots.
