ASTM A943 specifies the requirements for austenitic stainless steel pipes designed for high-temperature service. The grades covered under this specification include TP304H, TP309H, TP309HCb, TP310H, and TP310HCb. These materials are known for their excellent oxidation resistance and high-temperature strength.
The ASTM A943 standard outlines the manufacturing processes, mechanical properties, and chemical compositions required for these stainless steel pipes. The pipes are typically produced in a seamless form, which enhances their strength and durability.

While ASTM A943 grades are specifically designed for high-temperature applications, alternative grades that may be considered include:
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
