high quality 16mo3 steel steel for building structure

Steel pipe refers to the steel with openings at both ends and hollow section, and its length is larger than that of surrounding steel. According to the processing technology, it can be divided into seamless steel pipe and welded steel pipe, high quality 16Mo3 steel. The production methods mainly include hot rolling, cold rolling, extrusion, cold drawing, forging, welding, etc. The size range of steel pipe is very wide, from capillary with small diameter to large diameter pipe with several meters. Steel pipe can be used for pipeline, thermal equipment, mechanical industry, petroleum geological exploration, container, chemical industry and special purpose.

The addition of Ca element in steel such as high quality 16mo3 steel can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.

13CrMo4-5 steel plate delivery status and production process is strictly produced according to EN10028-2 standard. Delivery status: normalizing + tempering, tempering. The 13CrMo4-5 alloy plates thickness below 100mm, it is normalizing + tempering; Thickness 100mm-150mm, the plate is delivered in normalizing + tempering or quenched and tempered;150mm-250mm is delivered in tempered condition. The requirements for flaw detection levels, and Z-direction functional requirements can also be added.

high quality 16mo3 steel stock increased rapidly. The social stock of five kinds of steel products (screw steel, wire rod, hot rolled coil, cold rolled coil and medium and heavy plate) in major cities in China was 8.12 million tons at the end of January and 19.05 million tons at the end of February. By the middle of March, the social inventory was 20 million tons, an increase of 13.18 million tons or 193.3% over the end of December last year.
