Pure chromium ferritic stainless steel has no significant increase in hardness after quenching. During the forging process, work hardening will occur and the hardening degree varies with temperature and shape variables. This kind of steel has no rigorous requirement for the cooling temperature after forging. Ferritic stainless...

Stainless steel is widely used in chemical industry, petroleum industry, power plant, etc., and many products require not only corrosion resistance, but also high strength, so most stainless steels are used after forging. Compared with carbon steel, stainless steel has characteristics such as low thermal conductivity,...

Overheating If steel materials stay for too long in the high-temperature furnace, their grain will gradually grow and become coarse crystal. This phenomenon is called overheating. Overheating is related to heating temperature and heating time. The higher the heating temperature, the longer the time, the coarser the crystal...

When steel is heated, defects such as oxidation, decarburization, overheating, and overburning may be generated. For reducing and avoiding these defects so as to produce steel products with good quality, one should properly heat the steel material. Oxidation When the metal is heated to high temperature, the surface...

Choose the right places, warehouses 1. The places, warehouses for keeping steel materials should be cleaned, easy for drainage, away from the factories and mines that generate harmful gases or dust. Make sure to remove all the debris, weeds to keep the steel clean. 2. In the warehouse, salt, cement, and materials that...

PE pipes are commonly used in water supply system. So what are their classification and characteristics? Let's take a look. In China's municipal pipe market, drainage pipes and gas pipes are in great demand. And because PE (polyethylene) materials are of high strength,high temperature resistance, corrosion resistance,...

What are the general requirements for equipment layout design? 1. Meet the requirements of the process flow, and the disposition of equipment should be in the order of logistics. 2. The fire separation distance among equipment, buildings and structures should be in accordance with the requirements for production safety...
