PVQ A387 grade 11 class 1 boiler steel plate,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 09 The 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,PVQ A387 grade 11 class 1 boiler steel plate.

The alloy layer of clad wear-resistant plate is mainly made of chromium carbide, and it is also equipped with molybdenum, niobium, titanium, boron and other components. The formation of multi-element carbides also has strong stability at high temperatures and can still be maintained below 500 °. High hardness and good oxidation resistance. The new clad wear-resistant plate has multiple performances of wear resistance, corrosion resistance, temperature resistance and impact resistance.

PVQ A387 grade 11 class 1 boiler steel plate,Titanium microalloying is an element of 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 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.
