Product Description

scm440 normalized steel round bar

 

scm440 steel is a Chromium-Molybdenum through-hardening steel of medium hardenability. It is a general purpose high-tensile steel with medium strength level and good impact properties.


Normalized Steel Bar sometime is also one kind of annealing processing. It mainly changes the grain to remove the impurities in steel and improves the strength and hardness. For some hot rolled steel bars, to keep the basic mechanical properties, normalizing is often used.

 

scm440 normalized steel bar we supply includes following advantages:

Consistent mechanical properties

Deep mechanical properties (from surface to the center according to your requirement)

Even hardness on the whole bars/Tougher and Increased strength

No brittle, UT testing/Precision size tolerance/Good straightness

Good Roughness/Professional technical service/Competitive price/Fast delivery
