, Wear resistant steel plate refers to the special plate products used under large area wear condition. At present, the commonly used wear-resistant steel plates are made of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity by surfacing welding with a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance. In addition, there are cast wear-resistant steel plates and alloy quenched wear-resistant steel plates.
The requirements for toughness impact energy of , S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.
Our company will accept the product quality objection registration record, pass it to the production unit and relevant departments, and timely coordinate the supervision of product quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
We have new significant a283 material mild steel cost projects in Nigeria. It is about crude oil storage tanks. With the development of our steel materials business in the Africa those years, Nigeria has been an important market to us. And we have many famous projects in local and also participated in a lot of governmental projects. This crude oil storage tanks project is a very big engineering, and lasts for years. This is the only initial stage. We are under negotiation about following installation and further demands etc. matters.
