Welding hardox 400 specification steel heat treatment

A516Gr.65material is a carbon steel plate for medium and low temperature pressure vessels, which implements the ASTM A516 standard of the American Standard. The HARDOX 400 specification) product minimum thickness that can be provided is 8mm and the width is 1500~4000mm. It has sufficient strength and toughness, good welding performance and hot and cold processing performance. A516Gr.65 steel plate can be used to manufacture pressure vessel steel for petrochemical, gas separation and gas storage, oil storage tank and transportation equipment.

The chemical composition difference between HARDOX 400 specification, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between HARDOX 400 specification, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.

The company has our own truck fleet, and can transfer products flexibly and quickly. At the same time, we have large warehouses near the ports of Tianjin and Shanghai, so as to ensure that we can deliver high-quality products to customers in the first time. At the same time, it also greatly reduces the transportation cost, and realizes the double harvest of time benefit and economic benefit. Time guarantee is one of the important strengths of our service.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.

The Peru customer has cooperated with us since April 2015, and then they purchased 300 tons A36 mild steel plates as trial order. Since then, they book more than 1000 tons from us every time, and about two times every year. They asked SGS test every time. Through our cooperation those years, we have built very good relationship and they entrust us to buy other related HARDOX 400 specification products for them from China also. And they have introduced us good customers in Peru, among which there are also governmental projects. It is a win-win cooperation between us.

Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export HARDOX 400 specification to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.
