A709 Gr 50S bridge steel plate, NM series wear-resistant plates combine high hardness, high strength and high toughness, suitable for those severely worn occasions. The high wear resistance of the wear plate extends the service life of dump truck bodies, excavator buckets, crushers and similar equipment. The hardness of the wear-resistant steel plate is obtained through an effective quenching process. This method can not only achieve higher hardness, but also maintain a lower alloy composition in the steel. The produced wear-resistant plates are easy to machine, twist and weld.
JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with A709 Gr 50S bridge steel plate SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.
After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials.
