Ss 304 Seamless Pipe Introduction

304 stainless steel is a kind of common stainless steel materials, corrosion prevention is better than 200 series stainless steel materials. Resistance to high temperature also is better, generally use temperature limit is less than 650 °C. 304 stainless steel has good corrosion and corrosion resistance and better performance of resistance to intergranular corrosion.

For 304 stainless steel, the Ni element in its composition is very important, which directly determines the corrosion resistance of 304 stainless steel and its value.
The most important elements in 304 are Ni, Cr, but are not limited to these two elements. The specific requirements are stipulated by the product standard. Common judgments in the industry consider that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel. This is why the industry calls this type of stainless steel 18/8 stainless steel. In fact, the relevant product standards have very clear regulations for 304, and these product standards have some differences for different shapes of stainless steel. Below are some common product standards and tests.
To determine if a material is 304 stainless steel, it must meet the requirements of each element in the product standard. As long as there is a non-conformity, it cannot be called 304 stainless steel.

1, ASTM A276(Standard Specification for Stainless Steel Bars and Shapes)

2, ASTM A240(Chromium and Chromium-Nickel Stainless Steel Plate,Sheet, and Strip for Pressure vessel and for General Applications)

3, JIS G4305(cold-rolled stainless steel plate,sheet and strip)

4,JIS G4303 (Stainless steel bars)
