Requirements for chemical composition of hardox 500 welding

Titanium microalloying is an element of HARDOX 500 welding strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in HARDOX 500 welding tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.API 5L X42 steel plate (L290) is pipeline steel. API 5L X42 steel yield strength is 290 - 495 MPA, and the yield ratio is not more than 0.9. The HARDOX 500 welding delivery status of API 5L X42 steel plate is hot rolling or controlled rolling. API 5L X42 steel plate (L290) is mainly used for the production of oil and gas gathering and long-distance pipelines or coal and building material slurry pipelines, to serve for transportation of gas, water and oil in the natural gas industry.In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system.
