Machining EN10025-4 S420ML steel plates Hot Rolled Steel

EN10025-4 S420ML steel plates, Q215A steel belongs to carbon structural steel. Q215A steel does not contain specially added alloy elements. EN10025-4 S420ML steel plates, Q215A steel is mainly used in construction and engineering structures. Chemical composition of Q215A steel: C: ≤ 0.15, Si: ≤ 0.30, Mn: ≤ 1.20, P ≤: 0.045, S ≤: 0.050. Q215A steel has low carbon and manganese content. Q215A steel strength is slightly higher than Q195 steel strength. EN10025-4 S420ML steel plates, Q215A steel has good plasticity, good toughness, weldability and process performance. Q215A steel is mainly used in plant building, bridge components, tower, derrick and vehicle and ship manufacturing components.

In actual processing applications, the processing EN10025-4 S420ML steel plates thickness of flame cutting ranges from 6 to 200 mm, and the EN10025-4 S420ML steel plates cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting EN10025-4 S420ML steel plates with a certain thickness above 10mm.

We had a wonderful trip in Phuket Island, Thailand. At the end of 2019, in order to thank employees for their hard work for a year and enrich their lives, our company organized a pleasant trip to Phuket Island, Thailand. The tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5 o'clock in the afternoon on the 22th December.
