Description

321 stainless steel seamless pipe is a common austenitic 18/8 stainless steel alloy with titanium added, making it ideal for high temperature environments up to 900 ° C. It has good welding and forming capabilities and is widely used. Operating temperature environment exceeding 500 °C.

Advantage

It can destroy the cast structure of the ingot, refine the grain of the steel, and eliminate the defects of the microstructure, so that the steel structure is compacted and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, Hangzhou 321 stainless steel seamless pipe so that the steel is no longer isotropic to a certain extent; bubbles, cracks and looseness formed during pouring can also be used in high temperature and pressure Under welding.

Chemical composition(WT%)

(C) :≤0.08

(Si) :≤1.00

(Mn) :≤2.00

(Cr) :17.0 to 19.0

(P) :≤0.035

(S) :≤0.030

(Ni) : 9.0 to 12.0

(Ti): ≥5×C%

Application

Petrochemical industry, chemical fertilizer industry, oil refining industry, oil and gas industry, light industry and food industry, pulp and paper industry, energy and environmental industries.

How much the Ti composition should be in 321 stainless steel?

According to ASTM A182-2008, the Ti composition should be more than 4 times than the carbon composition but can not exceed 0.7%. Generally, the carbon composition in 321 stainless steel is less than 0.08%.

Picture

Through product innovation, we can enhance the added value of Chinese Factory Price 201 304 321 316 316L Seamless/Welded Stainless Steel Pipe/Tubes and improve the market competitiveness of products.
