Product Description

Ferritic stainless steel (400 series: Ferrite, martensitic ss) contains 15%~30% chromium and has a body - centered cubic crystal structure.This kind of steel generally does not contain nickel, and sometimes also contains a small amount of Mo, Ti, Nb and other elements. This kind of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, good stress corrosion resistance and so on. Ferritic stainless steel price is relatively low and stable, not only has many unique characteristics and advantages, has been proved that in many thought only adopts austenitic stainless steel (300) field of application of ferritic stainless steel is a kind of very excellent alternative materials, ferritic stainless steel containing nickel, the main elements for chromium (> 10%), and iron, chrome is special corrosion resistance of stainless steel element, its price is relatively stable.

409 stainless steel is commonly used ferritic stainless steel in mechanical and construction engineering.The presence of austenite grain greatly improves its mechanical properties.Many alloying elements have been added to improve the strength and hardness. The cheapest model, usually used as a car exhaust pipe.

416 stainless steel is a kind of steel with good cutting performance in stainless steel. 416 stainless steel is mainly used in the production of solenoid valves, micro-special motors and electrical components.The above materials are free cutting stainless
steel, especially suitable for automatic lathes, CNC lathes mass production.

420 stainless steel is called "blade grade" martensite steel and is similar to brinell high chromium steel, the earliest stainless steel.It is suitable for all kinds of precision machinery, bearings, electrical equipment, instruments, instruments, means of transportation, household appliances, etc.It is mainly used in manufacturing components that are resistant to corrosion by air, water vapor, water and oxidizing acid.Also used in surgery knives can be made very bright.

430 stainless steel is a universal steel with good corrosion resistance, better thermal conductivity than austenite, smaller coefficient of thermal expansion than austenite, thermal fatigue, add stabilizing element titanium, welding seam mechanical properties, but intergranular corrosion tendency.430 stainless steel for building decoration, fuel burner components, household
appliances, household appliances components.

904L stainless steel has good activity-passivation conversion ability and excellent corrosion resistance. It has good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid and phosphoric acid, good pitting resistance in neutral
chlorine-containing medium, and good crack corrosion resistance and stress corrosion resistance.Suitable for various
concentrations of sulfuric acid below 70℃, under normal pressure to withstand any concentration, any temperature of acetic acid, and acid and acetic acid mixed acid corrosion resistance is also very good.

410 stainless steel is martensite (high strength chromium steel), good wear resistance, corrosion resistance is poor.

SS 440 is high strength cutting tool steel, slightly higher carbon content, after the appropriate heat treatment can obtain higher yield strength, hardness can reach 58HRC, is one of the hardest stainless steel.The most common example is the razor blade.

*Storage: Pay attention to moisture, dust, oil, lubricating oil, as well as surface rust, or poor welding corrosion resistance.When water is immersed between the film and the steel substrate, the corrosion rate is faster than that without the film.Warehouse storage should be placed in a clean, dry and easy to open the air, to maintain the original packaging state, the stainless steel film should avoid direct light, film should be periodic inspection, if the film deterioration (film life of 6 months) should be replaced immediately, if the packing material when pad paper, in order to prevent surface corrosion should be
immediately removed pad paper.
