JIS SM490YB plates Boiler Steel Plate Exporter in India

We are a professional JIS SM490YB plates steel raw material supplier with a history of 17 years. After years of development, the company's steel plates and coils are widely used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields around the world. With good product JIS SM490YB plates quality, we have solid project cooperation with foreign governments or leading enterprises such as Egypt, Bangladesh, Myanmar, Thailand, Philippines, Vietnam, Venezuela, Peru, Mexico, the United States, Portugal, Russia, Iran, Iraq, Pakistan, etc.

The carbon content of JIS SM490YB plates, hot rolled steel plate is slightly higher than that of cold rolled steel plate. Hot rolled steel plate has low hardness, easy processing and good ductility. Cold rolled steel plate has high hardness and is difficult to process, but it is not easy to deform and has high strength. The strength of hot-rolled steel plate is relatively low, the surface quality (oxidation finish) is low, but the plasticity is good, and it is generally medium thick plate.

Alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel. Welding and forming of this steel plate JIS SM490YB plates should be avoided. It is best utilized wherever high resistance to fatigue and or impact is necessary. We can supply ASTM, JIS, DIN and GB various standards alloy steel grades.

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 JIS SM490YB plates 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.

JIS SM490YB plates, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of JIS SM490YB plates and No. 20 steel is 7.85kg/cm3

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
