The carbon content of P295GH steel hardness carbon structural steel is about 0.05% - 0.70%, some of which can be as high as 0.90%. Carbon structural steel can be divided into ordinary carbon structural steel and high-quality carbon structural steel. Carbon structural steel is mainly used in railway, bridge and all kinds of construction projects. Carbon structural steel p295gh steel hardness can be used to manufacture all kinds of metal components that bear static load and unimportant mechanical parts and general weldments that do not need heat treatment.

In order to improve the p295gh steel hardness corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main p295gh steel hardness coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking p295gh steel hardness sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.

p295gh steel hardness, P355GH plate mechanical properties: p355gh steel plate thickness/mm:> 60-100: tensile strength σb / MPa: 490-630; yield strength σx / MPa:> = 315 Impact absorption energy AKv / J:> = 34. Steel plate thickness / mm:> 100-150: tensile strength σb / MPa: 480-630,y ield strength σx / MPa:> = 295 Impact absorption energy AKv / J:> = 34. Chemical composition % (C:0.10-0.22, Si:<=03.60, Mn:1.00-1.70, Nb:<=0.010, Ti:<=0.03 S:<=0.030, P:<=0.025, Cr:<=0.30, Ni:<=0.30, Cu:<=0.30, Mo:<=0.10, V <=0.02)

Land transportation inquiry: (RMB fee) it is required to master the kilometers and towing price of major cities; packing price of each port area; customs clearance fee, commodity inspection fee, and animal and plant inspection fee standard. Key information to be clarified after accepting the consignation of the consignor (generally fax): shipping date, number of packages, box type, box quantity, gross weight and volume.
