ASTM A242 bar carbon steel plates

Our quality control department will do inspection for details of the steel materials ASTM A242 bar before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

The difference between application of 20# steel and Q345 steel. 20# steel is mainly used for making parts, which can be heat treated; Q345 steel is mainly used for making engineering structural parts, which is usually not heat treated. Q345 steel does not emphasize the composition, but its yield strength must be above 345mpa. Because the composition ASTM A242 bar is not fixed, Q345 steel is difficult to heat treatment (the temperature and time control of heat treatment are related to the composition, and different components use different processes).

ASTM A242 bar, 13CrMo44 steel plate is a kind of steel which with Cr, Mo,Cr-Mo and mainly used for pressure vessels. The steel grade 13CrMo44 is according to DIN 17155 standard which with the yield strength of 242MPa. The DIN 17155 13CrMo44 steel plate chemical composition is the content of C is 0.15, Mn is 2.00, S is 0.03, Cu is 0.30, Si is 1.00, P is 0.045, Cr is 17 or 19 and the Ni is 8 or 10.

If the chromium content in ASTM A242 bar 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.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.

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.
