ASTM A213 TP304 Superheater Stainless Steel Tubes

ASTM A213 TP304 Stainless Steel Tubes For Superheater And High-Temperature And High-Pressure Pipe Fittings

1. Description

The difference between 304, 304H and 304L

In fact, according to the content of chromium and nickel, all of them are 304 stainless steel, with 18% chromium (CR) and 8% nickel (Ni), but the main difference lies in the carbon content.

Among them, the highest carbon content is 304H, the lowest is 304L, and the carbon content of 304 stainless steel is between the two. The higher the carbon content, the worse the corrosion resistance of stainless steel. Different carbon content also leads to different prices. However, in actual use, different requirements for different uses are different.

ASTM A213 TP304 is a very mature steel,stainless steel pipe is the most widely used chromium nickel stainless steel. 304 stainless steel pipe has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. At the same time, it has good hot workability such as stamping and bending, and no heat treatment hardening phenomenon (non-magnetic, service temperature - 196 ℃ ~ 800 ℃). It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion.

ASTM A213 TP304 stainless steel seamless steel pipe for export can be spray marked on the surface, chamfered at both ends, and with pipe cap protective cover at both ends of the steel pipe. Various export packaging methods can ensure the safe transportation of products. Our stainless steel seamless steel pipe products are of good quality and various materials meet the different needs of customers. The products are now sold well all over the world, and have won the praise and satisfaction of customers. They are widely used in many fields.
