1.4021 stainless steel material
1.4021 is a stainless steel material, which is a martensitic stainless steel. 1.4021 contains 13% chromium and small amounts of carbon, manganese, silicon and other elements. Here are the main features of 1.4021:
High hardness: 1.4021 has high hardness and can be widely used in the manufacture of knives and cutting instruments, surgical instruments, springs, etc.
Good corrosion resistance: Due to its high chromium content, 1.4021 has good corrosion resistance and can be used in environments containing certain chemicals or in humid environments.
Medium weldability: 1.4021 can be processed and connected through conventional welding methods such as TIG and MIG, but appropriate preheating and cooling measures are required during the welding process.


Good handleability: 1.4021 is easy to control its hardness and mechanical properties during heat treatment.
Cheap: Compared with other stainless steel materials, 1.4021 has a lower cost.
It should be noted that 1.4021 is prone to hydrogen embrittlement rupture in certain highly corrosive environments, so careful selection and handling is required under specific conditions of use. In addition, 1.4021 is also prone to pitting corrosion and surface damage, so care and cleaning are required.
1.4021 is a martensitic stainless steel, also known as 420 stainless steel. Due to its excellent corrosion resistance, hardness, cutting performance and wear resistance, it is widely used in manufacturing knives, blades, medical equipment, mechanical parts, etc. Applications. The following are the development advantages and usage precautions of 1.4021:
