EN10025-2 S235J2 steel is equivalent to our Chinese teel grade Q235D. They are both done low temperature impact test at -20℃. Sometimes S235J2 would be used to built containers which can bear low temperature sea water. EN S460M steel, S235J2+N steel plate, following a rolling process within a certain temperature range, producing a material in a condition equivalent to that obtained after normalization. With the result that the specified mechanical properties values are conserved even after normalization treatment.

EN S460M steel, 35CrMo alloy steel is Chinese structual steel. As specified in GBT3077 standard, 35CrMo steel chemical composition should be: Carbon content 0.32-0.40 (C), Silicon content 0.17-0.37 (Si), Manganese content 0.40-0.70 (Mn), Chrome content 0.80-1.10 (Cr), Molybdenum content 0.15-0.25 (Mo). The heating temperature for 35CrMo alloy steel quenching is 850 Centigrade, the cooling material is oil. The heating temperature for 35CrMo alloy steel tempering is 550 Centigrade, the cooling material is oil or water.

Our company has the ability to produce all kinds of steel structure parts. At the same time, we can design drawings according to the requirements of customers, and process according to the drawings. EN S460M steel Heat treatment services - such as annealing, normalizing, quenching, tempering, quenching and tempering, solution treatment, etc. We can also heat treat according to customer's EN S460M steel requirements.

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.
