Waterproof Ss 304 Seamless Pipe , Welded And Seamless Pipe Corrosion Resistance
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)
| 304 | C | Mn | P | S | Si | Cr | Ni |
| % | ≤0.08 | ≤2.00 | ≤0.045 | ≤0.030 | ≤1.00 | 18.0–20.0 | 8.0-11.0 |
2, ASTM A240(Chromium and Chromium-Nickel Stainless Steel Plate,Sheet, and Strip for Pressure vessel and for General Applications)
