Description:

SUS304 refers to 304 stainless steel. SUS is a Japanese material standard, and 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. 304 is equivalent to our country's [1] (0Cr18Ni9) stainless steel. Japan also quoted the American name and called it: SUS304. [2]

 

Because it contains higher nickel and is austenitic single-phase structure at room temperature, it has higher corrosion resistance than Cr13 stainless steel, and has higher plasticity and toughness at low temperature, room temperature and high temperature, as well as higher Good cold forming and weldability. However, the strength at room temperature is low, the tendency of intergranular corrosion and stress corrosion is greater, and the machinability is poor. Austenite has no phase change when heated, so it cannot be strengthened by heat treatment.

 

Application field：

304 stainless steel is widely used in the production of corrosion-resistant and formability equipment and parts due to its good heat resistance. At present, 304 stainless steel has been widely used in food, chemical, atomic energy and other industrial equipment and decoration fields, as well as household products, cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical appliances, building materials, chemistry, food industry, agriculture, Ship parts.

 

characteristic

It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, no heat treatment hardening, and no magnetism.

 

 

Note: If the alloy powder has moisture absorption, or the storage period exceeds 3 months, it should be used before

Carry out drying treatment (150℃, heat preservation for 2 hours)
