420 and 430 stainless steel is mainly used for machining, than normal stainless steel has better cost performance, so in the case of corrosion resistance is not high requirements, has been more widely used. This steel can get better mechanical properties after quenching treatment, with good machinability, magnetic, good hardness, welding need to preheat.

Hot rolling is a metalworking process. Such as steel ingots or billets are difficult to deform and process at room temperature, they are generally heated to 1100 to 1250° for rolling, this rolling process is called hot rolling. Most steel materials are rolled by hot rolling, the steel delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can bestored in the open air. In addition, hot rolling is that it can destroy the casting structure of the ingot, refine the grain of the steel, eliminate structural defects, make the steel structure dense, and improve the hardness of the hot rolled steel.
Cold rolling refers to a rolling process that uses the pressure of rolls to squeeze steel to change the shape of the steel at room temperature. The advantafe of cold rolling is fast forming speed, high output, the coating is not damaged, and it can be made into a variety of cross-sectional forms to meet the needs of the use conditions. In addition, cold rolling can cause large plastic deformation of the steel, thereby increasing the yield point of the steel. Which is Widely used in home appliances and other industries.
What Are The Classes Of Stainless Steel?
Answer:
Classes of stainless steel are organized by their crystalline structure, mainly divided into martensitic, ferritic, austenitic, duplex, and precipitation-hardening. Austenitic is the most common, 321/321H is one of the austenitic stainless steel.
How Determine The Stainless Steel Grade For Your Needs?
Answer:
Magnetic Response — Some types of stainless steel grade are more magnetic than others. Adding chromium to a stainless steel tends to make it more magnetic, but adding nickel offsets or even eliminates the magnetism. Grade 310 are non-magnetic.
How Does Chromium Prevent Rusting?
Answer:
309/309S stainless steel contains chromium (22.0 min.-24.0 max). Chromium and other elements react with air and water to form a thin film on the outside of the steel. This film serves as a barrier that prevents corrosion.
