Alloy steel plate/sheet A573 Grade 65 structural quality

Hull structural steel is divided into general thickness and high-strength steel. General strength steel is divided into four grades of A, B, C and D; high-strength steel is divided into two strength grades and three quality grades; AH32, DH32, EH32, AH36, DH36, A573 Grade 65 structural quality, EH36. In order to ensure quality and ensure sufficient toughness of hull structural steel, the chemical composition of Mn / C is required to be above 2.5, and the carbon equivalent is also strictly required. Our Hull structural steel plates can be supplied with certificates from different classification societies.

The hardness of the steel plate is very high, so special equipment is needed to complete the processing and cutting of these materials, A573 Grade 65 structural quality. In order to cut the plate into an ideal size, the steel plate cutting needs to use natural gas flame for preheating, which will generate a large amount of oxygen flow during the operation. These substances will oxidize the steel plate, and then form a cutting edge, then the cutting operation process is basically completed. In the actual processing work, there are many different classifications for steel plate cutting.

Machining of A573 Grade 65 structural quality, wear resistant steel plate: wear resistant steel plate has good cutting and shearing properties. During machining, the cutting tools and feeding speed should be used reasonably according to the hardness of steel plate. Common tools are made of high speed steel or cemented carbide steel, and carbide surface tools are required for grinding. Wear resistant steel plate can be welded to structural steel by arc welding.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
