High carbon ferro- chrome

High carbon ferrochrome
Uses:

  (1)Used as the alloying agent of high carbon ball steel, tool steel and high-speed steel to improve the steel hardenability, increase the steel wear resistance and hardness.
  (2)Used as a cast iron additive to improve the cast steel wear resistance and improve the hardness, while enable the cast iron to have an excellent heat resistance.
  (3)Used as the chromium-containing raw material in the silicon-chromium alloy and middle, low and micro carbon chrome iron production with non-slag method.
  (4)Used as the chromium-containing raw material of chromium produced by electrolytic method.
  (5)Used as the raw materials of stainless steel smelting by oxygen blowing method.


  The product quality standard implements national standard GB/T5683-1987
Appearance quality

  There should be no visible non-metallic inclusions in the inner side and surface of high carbon ferrochrome; but small amount existence should be allowed when the cast ingot surface coating is not clean.

Packing

  The product is packed in woven bags, and the net weight is 1000kg of each bag.
Physical state
Natural blocks, the block weight should be not more than 15kg; the weight of iron chrome with the size less than 20*20mm should not exceed 55 of the total chrome weight.
