Q345E steel is low-alloy high-strength steel with good low-temperature impact properties. The grade of Q345E steel is composed of three parts: Chinese phonetic alphabet representing yield strength, yield strength value and quality grade symbol. Where: Q is the yield strength; 345 is the yield strength value in MPa; E is the grade (passing the - 40 degree impact test). sa573gr.70 size, Q345E steel is mainly used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, power stations, workshops, low-temperature pressure vessels, etc.
NM450 steel plate thickness≦80mm. sa573gr.70 size, NM450 wear-resistant steel plates are used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.NM450 Cchemical composition: C≤0.35; Si≤0.70; Mn≤1.70; P≤0.025; S≤0.010; Cr≤1.10; Ni≤0.80; Ti≤0.050; Mo≤0.55; B: 0.0005-0.006; Al≥0.010.

Automobile girder steel is a kind of low alloy hot-rolled steel plate with thickness of 2.5-12.0 mm for manufacturing automobile girder (longitudinal beam and cross beam). Due to the complex shape of automobile girder, good stamping performance is required in addition to high strength and cold bending performance for automobile girder steel. The sa573gr.70 size, medium thick and heavy steel plates are mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on.
Our company will accept the product quality objection registration record, pass it to the sa573gr.70 size production unit and relevant departments, and timely coordinate the supervision of product sa573gr.70 size quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
The high strength sa573gr.70 size low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of sa573gr.70 size ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
