Q235 SPCC SS400 SPHC 4 Hi Reversing Carbon Steel Stainless Steel
Strips Coils Cold Rolling Mill
1. Product description
Cold rolled steel can exhibit strength up to 20% greater than that
of hot rolled steel, which makes it more suitable for use in
high-stress applications. Better surface finishes: Parts and
products made from cold rolled steel generally have a smooth and
shiny surface that is free of rust and scale.
2. Main function
It is used for reversible rolling of high precision and good
performance plain carbon steel, stainless steel and low alloy
steel.
