Our company is China's 10th largest supplier & Exporter of stainless steel, carbon steel plate and section, alloy steel plate and pipes. We are specialized in stocking & distributing various Stainless Steel, carbon steel plates, BS700MC heat treatment angle steel, H beam steel to worldwide for specific & urgent requirements. We have a fully advanced and modernized warehouse that stores tonnes of our value-adding BS700MC heat treatment products, which we source out from the mills that are compliant with the universal guidelines for plate production.

Under the specification EN 10025-2, S275J2 plates are mainly used in the building industry and mechanical engineering, containers,storage tanks and roll formed steel profiles,such as steel angles, steel structures, H-beams, T-sections. For BS700MC heat treatment, S275J2 carbon steel, our engineers still suggest done normalized heat treatment for them if customers want to improve their steel's property when using. Else, this steel must be done low temperature impacting test at -20℃.

Compared with BS700MC heat treatment, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while BS700MC heat treatment is not.

The steel such as BS700MC heat treatment delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

BS700MC heat treatment, Q345 and Q345B are steel numbers. The differences are as follows:1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.

We have a good inventory system because of which the alloy steel plates and structural steel sheets are supplied and delivered to our customers on time. Our alloy steel plate is significantly affordable than austenitic BS700MC heat treatment stainless steel which helps to reduce maintenance and full life costs – as well as improved safety over standard boilerplate. Contact us today to request a quotation or email us with your complete specification, we are happy to help you!

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 BS700MC heat treatment 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.
