S690Q material structural steel

The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, S690Q material steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and S690Q material carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.

A517 Grade Q steel is a low-alloy pressure vessel grade rolled steel plate that conforms to A20 manufacturing specifications; in an open-hearth under oxygen or via electric arc production. These plates have a maximum thickness of 32mm S690Q material and must be subjected to robust heat analysis to verify its elemental composition. Process managers must carefully control the levels of carbon, manganese, phosphorous, sulfur, silicon, chromium, molybdenum, boron, vanadium, and titanium in order to guarantee compliance – thus performance.

Manganese steel plates emerge as a profitable solution to diverse kinds of acid attacks. These have qualities surpassing an ordinary steel plate. Neither fully austenitic nor ferritic, these plates S690Q material provide boosted resistance to chloride stress corrosion cracking, which the 300 series stainless steel plates are susceptible to. 22% Chromium allows these plates to withstand Sulphuric and Hydrochloric acid attacks, whereas Molybdenum (up to 3%) avoids crevice and pitting corrosion.

WTST 37-3 steel plate is a kind of carbon steel plate. WTST 37-3 steel plate can be used to build low temperature sea water resistant containers. When the customer orders S690Q material WTST 37-3 steel plate from us, our factory should roll it in full accordance with SEW 087-2 specification, and the factory will issue the original mill test certificate for inspection before delivery.

Chemical composition of 12Cr1MoV alloy steel plate: Carbon C: 0.08-0.15; Silicon Si: 0.17-0.37; Manganese Mn: 0.40-0.70; Sulfur S: allowable residual content ≤ 0.035; Phosphorus P: allowable residual content ≤ 0.035; Chromium Cr: 0.90-1.20; Nickel Ni: allowable residual content ≤ 0.030; Cu: allowable residual content ≤ 0.030; V: 0.15-0.30; Mo: 0.25-0.30.Delivery status of S690Q material, 12Cr1MoV alloy steel plate: delivered in heat treatment (normalizing, annealing or high temperature tempering) or non heat treatment status, and the delivery status shall be indicated in the contract.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel S690Q material products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
