S235J0W cold rolled steel strips and a36 plate specification

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

P355NL1 steel plate is alloy special steel, steel for pressure equipment, with good plasticity, toughness, cold bending performance and welding performance. The steel is used to manufacture spherical storage tanks of more than 50 cubic meters, and can also be used to manufacture single-layer coil welding vessels, multi-layer hot-sleeve coil welding vessels, second and third category vessels and low-temperature pressure vessels.

Pressure vessel steel plates are mainly used for manufacturing pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of pressure vessel steel plates ranges from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature ranges from - 20 °C to 450 °C. In addition to certain strength, good plasticity and toughness, pressure vessel steel plates must also have good cold bending and welding properties. Q245R, Q345R, 14Cr1MoR, 15CrMoR, S235J0W cold rolled steel strips etc. are common pressure vessel steel grades.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the S235J0W cold rolled steel strips quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After S235J0W cold rolled steel strips quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers.
