Stainless steel plate plays a role is not to let it rust, black and white and black and white iron iron manufacturing as ordinary steel will rust, but this does not invade the rust corrosion to steel, stainless steel plate can be said that this is like a wolf in sheep's clothing, although the appearance is rusty but the inside is still good.
Black and white iron and stainless steel is an alloy, but ferrous alloy content is relatively low, stainless steel alloy materials such as what kind of phosphorus, copper, and so on alloy content is relatively high.
Different specifications contain different amounts of alloy elements, but the content of alloying elements in stainless steel is the lowest at ten percent.
The contents of the alloy elements in black and white iron are only a few percent, and some even lower specification weather resistant steel, those alloy elements content is only 0.1 percent.
With the rapid development of black and white iron processing technology, there appears a black iron fire, the fire has the strong performance of the black and white iron, some do not need specific local fire protection coating, fireproof coating materials that can be used to replace the black and white iron.
And black and white iron fire performance, unlike those of fire protection coating needs regular repairs, black and white iron fire has long-term unchanged characteristics.
