Product Description
Gas Cyliner Precise Seamless Steel tube
The steel can suffer high pressure is usually known chromium molybdenum steel quenched and tempered as 34CrMo4 grade in international standards with following limitations.
The Chemical Composition of Gas Cyliner Precise Seamless Steel tube:
Steels shall be aluminum and/or silicon fully killed and produced to fine grain practice. The chemical composition of all steels shall be declared and defined at least by:
a) carbon, manganese, aluminum and silicon contents in all case;
b) Nickel, chromium, molybdenum, and any other alloying elements intentionally added.
The Mechanical properties of Cold Processing Gas Cyliner Precise Seamless Steel tube
Mechanical properties simulated on quenched and tempered sample shall with following requirement
at room temperature: (Except impact strength, all other properties are measured at ambient temperature)
-- Tensile strength (according to ISO6892) 982 to 1100MPa
-- Yield strength (according to ISO6892) 750 to 933 MPa
