Wide thick rolling bridge pattern two-edged blade

1.Twenty-four year professional experience
2.We are END MANUFACTURER
3.Competitive price
4.OEM and ODM
5.We make steel by ourselves,so the materials are various .
6.All products are from forged steel billet,not from steel plate.Forging steel make the inside microstructure become much closer and the metal grain size becomes much smaller to ensure a long worklife.
7.Specializes in shearing machine blades,slitting machine knives and other cutting tools for industrial machines .
8.Blade:maximum length of 5800mm and maximum diameter of 1500mm
9.Materials:5CrW2Si, 6CrW2Si, Cr12MoV, 9CrSi, H13 and self-developed H13k, HMB and HMK high various alloy steel
10.High intensity, high hardness, high toughness, and high hardenability, etc.
11.Widely used in industries of steel, rubber, papermaking, and so on.
12.Passed the ISO9001 quality certification in 2001,Each technical index reaches the international standard.
