We have a very NV D36 ore carrier steel extensive commodity information network, with partners all over the world, and have become the full authority of many European and American traders in China. Under the guidance of the business philosophy of "creating the best service" and through the unremitting efforts of all employees, we have achieved remarkable results.
As people have higher and higher requirements for the quality of various steel processing products, the market demand for NV D36 ore carrier steel, pickling steel coils is getting better and better. At present, they are mainly concentrated in the automotive industry, compressor industry, machinery manufacturing industry, spare parts processing industry, fan Industry, motorcycle industry, steel furniture, hardware accessories, electric cabinet shelves and various shapes of stamping parts. With the advancement of technology, hot-rolled pickled steel plates are currently involved in home appliances, containers, electrical control cabinets and other industries.
Cold rolled steel sheet has high strength, high hardness, high surface finish and is generally thin plate, which can be used for stamping. The production process of NV D36 ore carrier steel, hot-rolled and cold-rolled steel plates is different. Hot rolled steel plate is rolled at high temperature, while cold rolled steel plate is rolled at normal temperature. Generally speaking, cold-rolled steel plate has better strength and hot-rolled steel plate has better ductility.
With the increase of temperature, the yield limit of NV D36 ore carrier steel will decrease monotonically, but the tensile strength of NV D36 ore carrier steel will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of NV D36 ore carrier steel. Near the blue brittleness temperature, the NV D36 ore carrier steel strength increases and the plasticity decreases. The elongation and section shrinkage of NV D36 ore carrier steel increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
The S355 steel material itself is divided into many grades, so it cannot be said that S355 is equivalent to which grade of the national standard Q345, NV D36 ore carrier steel. In engineering, usually S355JR steel is equivalent to Q345B steel, S355J0 steel is equivalent to Q345C steel, S355J2 steel is equivalent to Q345D steel, S355N steel is equivalent to Q345D steel, and S355NL steel is equivalent to Q345E steel.
S355J2 hot rolled steel plate executive standard: EN10025-2S355J2 hot rolled steel plate delivery status: control binding, normalizing rolling, normalizingThe European standard S355J2 hot rolled steel plate is available from NV D36 ore carrier steel stock and can be cut and processed according to the requirements of customers; the futures can be produced according to your requirements, and our S355J2 hot rolled steel plate price is preferential and the delivery time is fast, welcome to contact and purchase.
