The main types of stainless steel features

304: as a kind of widely used steel has good corrosion resistance, heat resistance, low temperature and mechanical intensity, punching, bending, such as hot workability is good, no heat treatment hardening phenomenon, nonmagnetic, using temperature is -193 degrees to 800 degrees.
Purpose: tableware, kitchen utensils and appliances, water heaters, boilers, auto parts, medical equipment, food machinery, wine storage, pressure vessels(chemical machinery, chemical equipment).
304 l: after welding and eliminate stress, its corrosion resistance good, under the condition of without heat treatment, can also keep good corrosion resistance, in 400 degrees commonly used.
Purpose: petrochemical industry, building materials.

 316:316 as low carbon, add MO element, so its corrosion resistance and atmospheric corrosion resistance and high temperature strength performance is very good, can be used in harsh conditions, suitable for use under 900 degrees, and nonmagnetic.
 Purpose: the equipment used in sea water, chemicals, dye, the papermaking, acetic acid, fertilizer and other production equipment, facilities, food industry and coastal areas to fight between crystal corrosion products with special requirements.

powder metallurgy stain—less steels
Powder metallurgy stainless steel is made of stainless steel powder metallurgy, it is a kind of powder metallurgy material, can be made into steel or parts.Its advantage is to reduce the alloying elements segregation, refine microstructure, improve performance, save raw materials, save energy, reduce the cost.
