Q345E steel plate is a low-alloy high-strength steel plate with good low-temperature impact performance. The steel grade is composed of three parts: Q (Qufu in Chinese spelling) representing yield strength, yield strength value, and quality grade symbol. shipbuilding use GL-D32 weldable steel, Among them: Q represents the yield strength; 345 represents the yield strength value, unit MPa; E represents the grade (passed -40 degrees impact test).
In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials shipbuilding use GL-D32 weldable steel used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.
The purpose of shipbuilding use GL-D32 weldable steel quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of shipbuilding use GL-D32 weldable steel. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
ST37-2 is a kind of low carbon steel with carbon content of 0.20%, similar to S235JR or Q235 shipbuilding use GL-D32 weldable steel. It's not as strong as common ASTM A36, but it is also widely applied by everyday uses and structural applications where high strength is not so important. Equal ST37-2 angle steel size: shipbuilding use GL-D32 weldable steel Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 - 35 mm. Length: 6 m, 9 m or as required. Unequal ST37-2 angle steel size: shipbuilding use GL-D32 weldable steel Size: 30 × 20 mm to 250 × 90 mm. Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.
When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
