The performance requirements of heat treatment of p355gh

Pageviews:

After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of heat treatment of P355GH, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions

The heat treatment of p355gh processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the heat treatment of p355gh steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.
