27SiMn seamless steel pipe introduction

27SiMn seamless steel pipe is a low-alloy high-strength structural steel, belonging to the low-alloy high-strength steel series.

Compared with Q235, the yield strength of 27SiMn steel is increased by 20-40MPa; the tensile strength is increased by 10-15MPa; the elongation is decreased by 15-20%, and the comprehensive mechanical properties are improved.

27simn seamless steel pipe, namely 27 silicon manganese seamless steel pipe, is one of the materials of seamless steel pipe, the carbon content is between 0.24-0.32%, simn is single because it is because of the five elements (carbon C, silicon Si, manganese) Mn, phosphorus P, sulfur S), the content of silicon manganese is about 1.10-1.40%.

Main features of 27simn seamless steel pipe:
The performance of 27simn steel is better than that of 30Mn2 steel, the hardenability is high, the critical hardenable diameter in water is 8~22mm, the machinability is good, and the cold deformation plasticity and weldability are moderate.

27simn seamless steel pipe application:
It is used to manufacture hot stamping parts that require high toughness and wear resistance; it can also be used in normalized or hot rolled supply state, such as track pins of tractors, etc.
