SUS304 คืออะไร

SUS304 (SUS meaning Steel Use Stainless) stainless steel austenite is typically known as the Japanese name for SS304 or AISI 304. The main difference between the two materials is not any physical property or feature, but how it is referenced in American and Japanese grades. However, that has not stopped various people from attempting to explain the mechanical differences between the two grades.

SUS304 (Japanese JIS Standard) is one of the most widely used versions of stainless steel. It is made up of 18% Cr (Chromium) and 8% Ni (Nickel). In high and low temperatures, it can maintain its strength and heat resistance. It also has great weldability, mechanical properties, cold workability and corrosion resistance at room temperature.

SS304 (AISI 304) is the most frequently used stainless steel when making other stainless steel materials and is typically bought in a cold or annealed condition. Similar to SUS304, SS304 also contains 18% Cr and 8% Ni and is, therefore, referred to as 18/8.

SS304 has great weldability, heat and corrosion resistance, low-temperature strength, processability, mechanical properties, no hardening from heat treatment, and great warm workability like bending and stamping. SS304 is used in a vast array of applications in many industries, including food, medical and decoration work.
