Cusomized Seamless Cold Drawn Steel Tube with Black Annealed Out Surface 27SiMn
OVERVIEW
The material 27SiMn has high hardenability. 27SiMn teel’s toughness decreases not much
as heat treatment, but material 27SiMn has very high strength and
abrasion resistance, especially when water quench, grade 27SiMn
still has high toughness. However 27SiMn steel is sensitivity to
the white dots very much and 27SiMn is sensitivity to temper
brittleness tendency and overheating when heat treatment.
27SiMn is mainly used under tempering condition and used in the
manufacture of high toughness and wear resistance of hot
stamping.27SiMn can also used under fire or hot rolling using
supply condition, such as the tractor caterpillar pin, etc.
APPERANCE
Tube shall have a smooth internal and external surface consistent with cold working process, tube inner surface should be free from rust, scratches and other surface irregularities.
USAGE SCOPE
Honed tube for hydraulic cylinder, swivel crane, injection machine and construction machine application
