According to the data released by the world iron and Steel Association, the world pig iron production in March 2020 was 103 million tons, a year-on-year decrease of 3.5%, a year-on-year increase of 1.8% in February, and the overseas pig iron S700MC high strength alloy steel production excluding China was 36.309 million tons, a year-on-year decrease of 11%. In March, except for China and Russia, pig iron production increased by 1%6, other countries' pig iron S700MC high strength alloy steel production decreased year-on-year, with 28 EU countries reducing by 14.2%, 3 CIS countries (Russia, Ukraine and Kazakhstan) reducing by 0.8%, India reducing by 14.6%, Japan reducing by 7.9% and South Korea reducing by 9.5%.
Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.
With the fast development in Myanmar, Myanmar navy build frigate every year. We Cooperate with Myanmar Navy from 2015. They purchased 412 ton LR AH36 steel plate from us as trial order in 2015. After receiving the S700MC high strength alloy steel goods, they speak highly of the quality and our service. After that they purchase the shipbuilding steel plate from us regularly. In May,2018, the Myanmar navy’s local representative visit our office and production line, and sign another contract 2025 ton steel order in our office.
If the chromium content in S700MC high strength alloy steel alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.
The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. S700MC high strength alloy steel, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.
Firmly establish the "people-oriented, safe development" concept, strictly follow the safety production policy of "safety first, prevention first, comprehensive management", strengthen and improve the management and supervision of safety production in an all-round way, and strive to improve the controllability of safety management And effectiveness, cultivate safety culture, improve long-term safety production mechanism, and build a harmonious BEBON.
