SPV450 Steel plate Annealing and Normalizing

SPV450 Steel plate Annealing and Normalizing

SPV450 Steel Annealing: Annealing, in metallurgy and materials science, is a heat treatment wherein a SPV450 material is altered, causing changes in its properties such as hardness and ductility. It is a process that produces conditions by heating to above the SPV450 critical temperature, maintaining a suitable temperature, and then cooling.  SPV450 Annealing is used to induce ductility, soften material, relieve internal stresses, refine the structure by making it homogeneous, and improve cold working properties.

SPV450 Steel Normalizing: Normalizing is a type of heat treatment applicable to ferrous metals only. It differs from annealing in that the SPV450 metal heated to a higher temperature and then removed from the furnace for air cooling. The purpose of SPV450 normalizing is to remove the internal stresses induced by heat treating, welding, casting, forging, forming, or machining. Stress, if not controlled, leads to metal failure; Therefore, before hardening SPV450 steel, you should normalize it first to ensure the maximum desired results.

P690Q steel plate Tempering

P690Q steel plate Tempering

P690Q Steel Tempering: Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the P690Q alloy. The reduction in hardness is usually accompanied by an increase in P690Q ductility, thereby decreasing the brittleness of the P690Q metal. Tempering is usually performed after quenching, which is rapid cooling of the P690Q steel to put it in its hardest state.

Tempering is accomplished by controlled heating of the quenched work-piece to a temperature below its "lower critical temperature". This is also called the lower transformation temperature or lower arrest temperature; the temperature at which the crystalline phases of the alloy, called ferrite and cementite, begin combining to form a single-phase solid solution referred to as austenite. Heating above this temperature is avoided, so as not to destroy the very-hard, quenched microstructure, called martensite.

A387 Class2 Grade 11 steel plate cutting process

A387 Class2 Grade 11 steel plate cutting process

When automaticly cutting, hanging A387 Class2 Grade 11 steel plate to gas cutting platform, and A387 Class2 Grade 11 steel plate should be adjusted unilaterally two ends the distance difference between the guide rail and within 5 mm. When making semi-automatic cutting, A387 Class2 Grade 11 steel plate should be cut, and then put the cutting machine lightly on the guide rail. Make a cutting torch on one side of the manipulator, oriented according to A387 Class2 Grade 11 the thickness of the steel plate cutting nozzle, at same time adjusting the cutting and cutting speed.

According to the different methods of automatic cutting and semi-automatic cutting, adjust the distance of each the cutting torch after amount, and considering the slotting compensation; In the process of A387 Class2 Grade 11 steel plate cutting, cutting the size of the Angle and direction depend on the thickness of the steel plate.

In A387 Class2 Grade 11 plate cutting, cutting nozzle and the workpiece surface remain vertical, after waiting for the whole cross-section slice through mobile cutting nozzle, turn into normal gas cutting, gas cutting should be slightly slow down is going to reach the finish line, that the lower part of incision completely cut off.

A203 Grade B steel plate gas cutting

A203 Grade B steel plate gas cutting

A203 Grade B steel plate gas cutting parameters is adjusted according to A203 Grade B thickness . Cutting parameters included cutting nozzle model, oxygen pressure, cutting speed and preheating flames of energy, such as the selection of process parameters is mainly according to the type of gas cutting machine and cutting thickness, as for no cutting A203 Grade B steel, takes an exam the similar steel plate cutting, cutting parameters, check the gas flowing cut chew at the same time.

Removing A203 Grade B steel surface dirt should be done before gas cutting, grease, and set aside space below, to facilitate the blowing out of slag. Gas cutting, the cutting torch movement should maintain a constant speed. A203 Grade B cut distance on the surface of the flame core tip with 2 ~ 5 mm will be advisable, too close will melt incision edge, too far will insufficient heat, easy to interrupt the cuting process.

In A203 Grade B plate cutting process, preheat flame should be big,and  burning air flow length should exceed 1/3 of the workpiece thickness. Cutting nozzle and A203 Grade B steel surface should be about 10 ° ~ 20 ° inclination, which will make A203 Grade B steel plate edge uniform heat.

Stamping Process of HI steel plate

Stamping Process of HI steel plate

Stamping comes from impact to HI pipes, HI strip and HI plate, profiles. Such as external force, to make material deform or separate, so that to obtain the required shape and size. This forming method is called stamping.

Stamping and forging are both belong to plastic processing (or pressure processing), and they can be called the forging press together. The raw material of HI strip and HI steel plate can be hot rolled and cold rolled steel. Among all steel in the world,  60 ~ 70% is plate. And most of the plate need punching into finished products.Such as car body, chassis, fuel tank, radiator fin, boiler drum, the container shell, motor, electric iron core silicon steel sheets. And in other fields, like instruments and meters, household appliances, bicycles, office machinery, household utensils, and other products, also need a large number of stamping parts.

Shanghai Katalor is specialized in HI steel plate material whose business related with trade,processing,storage and transportation for more than ten years.If you have any needs and doubts about this material, please contact us at your convenience.
