A334 Low Temperature Alloy Pipe

ASTM A334 alloy Steel Press Pipe

ASTM A334 Grade 1 Carbon Steel Pipe is a premium alloy steel pipe with excellent resistance to impact and bending stress, and remains stable under extreme temperature and pressure conditions. The pipe's superior performance is due to the presence of elements such as manganese, molybdenum and silicon, which significantly increase its strength and durability. What's even more valuable is that ASTM A334 Grade 1 carbon steel pipe is not only corrosion-resistant, but also has good heat treatment properties.
ASTM A334 Grade 1 cryogenic steel pipe has a minimum tensile strength of 380 MPa and a minimum yield strength of 205 MPa, enabling it to meet the needs of a variety of applications. In order to meet the needs of different temperature ranges and specific applications, ASTM A334 carbon steel seamless pipes also provide a variety of types or grades to choose from, including grade 3, grade 4, grade 6, grade 7, grade 8 and grade 9, etc.
