08cupvre steel equivalent and EN 10155 S355J0WP are weather resistant steel plate

Q355GNH weathering steel: Q——The first letter of the Chinese pinyin of "Qu" in the yield strength;355——The lower limit of the lower yield strength of steel, in N/mm²;GNH——respectively the first letter of "Gao, Nai, Hou" Chinese Pinyin;Quality grades are divided into A, B, C, D, E(1)Q355GNH executive standard: GB/T 4171-2008(2)Q355GNH smelting method: the steel is smelted by converter or electric furnace, and it is killed steel.

The company will also put Georgetown steelworks on "care and maintenance mode" and temporarily lay off or redeploy about 130 employees working at the steelworks and contractors while some 08CUPVRE steel equivalent maintenance employees will be on staff during the closure. It is stated that unemployment insurance and state-based unemployment support will be available immediately to workers affected by these changes.

The toughness of steel such as 08CUPVRE steel equivalent is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.

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 08CUPVRE steel equivalent 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.
