What is the difference between Q235A steel and Q235B steel? First, The carbon content of Q235A steel is 0.22%, higher than that of Q235B steel, which is 0.20%. The sulfur content of Q235A steel is 0.050%, higher than that of Q235B steel, which is 0.045%. Second, S355NL indian equivalent, Q235 material belongs to carbon structural steel. The English letters A and B at the back have different meanings. They are impact temperature requirements. Q235A steel is not subject to impact, while Q235B steel is subject to 20 ℃ room temperature impact.
Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < S355NL indian equivalent steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished S355NL indian equivalent product packaging.
SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. S355NL indian equivalent, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the S355NL indian equivalent steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
