304H Stainless Steel Seamless Tube

ASTM A213 TP304ļ¼Œ 304Lļ¼Œ 304H Seamless Tube For Heat Exchanger And Boiler

TONG CHUANG Group is one of the large manufacturer of stainless steel pipes in Chinaļ¼Œ widely used in boilersļ¼Œ heat exchangersļ¼Œ and other equipment. We have trade relations with more than 40 countries and have won customer satisfaction with timely delivery and strict quality control.

 

ASTM A213 TP304 Seamless Tubeļ¼Œ Stainless heat-resistant steel with good bending and welding process performanceļ¼Œ corrosion resistanceļ¼Œ high lasting strength and organizational stabilityļ¼Œ and very good cold deformation capacity. Use temperature up to 650 ā„ƒļ¼Œ oxidation resistance temperature up to 850 ā„ƒ. Applications: Used in the manufacture of large generating set boiler superheater tubesļ¼Œ reheater tubesļ¼Œ steam pipes and heat exchange tubes for petrochemicals. The allowable oxidation resistance temperature for boiler tubes is 705°C.

 

 

What is the difference between 304ļ¼Œ 304L and 304H stainless steel?

 

1.There are hundreds of different grades of stainless steel on the market. Each of these unique stainless steel formulations offers a degree of corrosion resistance superior to that of ordinary steel.

 

2.The presence of these stainless steel variants can cause some confusion – especially when the names and formulations of the two stainless steel alloys are nearly identical. This is the case with 304 and 304L stainless steel.

These three alloys are very similarļ¼Œ but there is one key difference. The maximum carbon content of 304 stainless steel is 0.08%ļ¼Œ while the maximum carbon content of 304L stainless steel is 0.03%. The "L" in 304L can be understood to mean ultra-low carbon.

This 0.05% difference in carbon content results in a slight but significant difference in the properties of the two alloys.

 

 

Mechanical difference

 

Compared to the "standard" grade 304 stainless steel alloyļ¼Œ grade 304L has a slight but significant reduction in key mechanical properties.
