hardess of nm500 steel plate Carbon Steel Supplier

CortenB vs 45#: Corten B medium-carbon quenched and tempered steel has higher strength, toughness and hardenability than 45# steel. Corten B steel can obtain better comprehensive mechanical properties after quenching and tempering. The cutting performance is still good, but the welding performance is poor, the cold deformation plasticity is low, and the temper brittleness tendency. It is generally used in quenched and tempered state, and can also be used in quenched, tempered or normalized state.

Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, hardess of NM500 steel plate are strict. In the chemical composition of boiler steel, hardess of NM500 steel plate, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.

As the thickness and hardness of hardess of NM500 steel plate increase, the tendency to crack at the cutting edge increases. In order to prevent the hardess of NM500 steel plate from cutting cracks, preheating should be carried out before hardess of NM500 steel plate cutting. Special attention should be paid to preheating to make the entire hardess of NM500 steel plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole hardess of NM500 steel plate cannot be preheated, the partial preheating method can be used instead.
