Frequently Asked Questions

What is the carbon content limit for ASTM A269/270/213 TP304L?

The carbon content for the low-carbon variant of TP304L is restricted to C ≤ 0.035% under ASTM A269/270/213 standards, which helps minimize carbide formation.

How does the low carbon content benefit welded structures?

By keeping the carbon content low, the material prevents chromium carbide precipitation during welding. This significantly reduces intergranular corrosion, making it suitable for corrosive environments.

What are the mechanical strength properties of ASTM A213 TP304L?

According to the specification parameters, ASTM A213 TP304L has a minimum tensile strength of 485 MPa, a minimum yield strength (0.2% Proof) of 170 MPa, and a minimum elongation of 35% in 50mm.

What are the equivalent international grades for TP304L?

Equivalent grades include China (GB) 06Cr19Ni10 (022Cr19Ni10), U.S. 304L (UNS S30403), Europe (EN) 1.4307 (X2CrNi18-9), Japan (JIS) SUS304L, Germany (DIN) X2CrNi18-9 (1.4307), and Russia (GOST) 03Kh18N11.

What types of inspections are performed on these steel pipes?

The material undergoes 100% PMI testing, is certified with the EN10204.3.1B Mill Test Certificate, and third-party inspections are accepted.
