Stainless Steel Cup

The stainless steel cups currently on the market are mainly made of 304 stainless steel. 

304 stainless steel is a nationally recognized food grade stainless steel. It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties.It has good hot workability such as stamping and bending without heat treatment. Hardening phenomenon (use temperature -196℃～800℃)

Advantage:

1.Stainless steel material, sturdy, not fragile, durable, and beautiful

2.Can be used for a long time

3.Good keep temperature performance

Disadvantage:

1.Chloride ion: stainless steel corrodes quickly in the presence of chloride ion, even more than ordinary low carbon steel. Therefore, there are requirements for the use environment of stainless steel, and it needs to be wiped frequently to remove dust and keep it clean and dry.

2. Solution treatment: The alloy elements are not dissolved into the matrix, resulting in low alloy content in the matrix structure and poor corrosion resistance. 

3. Intergranular corrosion: This material without titanium and niobium has the tendency of intergranular corrosion.
