Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important P265GH steel usage heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.

The difference between Q235 steel and Q345 steel:The lower limit of yield strength of Q235 steel is 235MPa, the lower limit of yield strength of Q345 steel is 345MPa. The p265gh steel usage alloy content of Q235 steel is common carbon steel and Q345 steel is low alloy steel. Q345 steel is used for structures, mechanical parts, building structures, general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, p265gh steel usage mining machinery, power stations, bridges, etc..

S235JR steel plate is one mainly of Carbon and low alloy steel, S235JR steel plate is a type of steel sheet under EN standard which is used to build ship, bridge, belongs to high strength sheet. EN10025-2 S235JR is equivalent to DIN:ST37-2,JIS:SS400,ASTM:A283C, GB Q235B and UNI:FE360B.

As the thickness and hardness of p265gh steel usage increase, the tendency to crack at the cutting edge increases. In order to prevent the p265gh steel usage from cutting cracks, preheating should be carried out before p265gh steel usage cutting. Special attention should be paid to preheating to make the entire p265gh steel usage interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole p265gh steel usage cannot be preheated, the partial preheating method can be used instead.

42CrMo alloy steel p265gh steel usage: low temperature tempering welding performance thermal processingThe heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel p265gh steel usage plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
