S420NL carbon steel material Heavy Plates Cutting

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from S420NL carbon steel material. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.

Titanium microalloying is an element of S420NL carbon steel material 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 S420NL carbon steel material 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.
