The cold working performance of P355GH boiler steel elongation and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of p355gh boiler steel elongation and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.

Heat treatment of p355gh boiler steel elongation, SA516Gr415 vessel plate: SA516GR60 steel plate is not more than 1.5in(40mm) in thickness is usually supplied in rolling condition, and steel plate can also be normalized or stress relieved, or tempered by normalizing. SA516GR60 steel plate with thickness greater than 1.5in. (40mm) shall be normalized. If the buyer agrees, SA516GR55, SA516GR60 and SA516Gr70 can choose cooling rate greater than in air to improve the durability, but the steel plate shall be tempered within 1100-1300 degrees F (595-705).

We have efficient and quick logistic team service. We promise that after the customer places the order, the spot products will be shipped, processed, and cut on the same day. The steel p355gh boiler steel elongation products will be shipped in 2-5 days according to the characteristics of the product. The company has always been adhering to the service concept of "integrity, pragmatism, enthusiasm" and dedicated to providing our customers with high-quality steel products and after-sales service.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and p355gh boiler steel elongation pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
