The denisty of 09CuPCrNi-B stock properties price list

Chemical composition of denisty of 09CUPCRNI-B, Q420qENH steel plate:Carbon C: not more than 0.11, silicon Si: 0.15-0.50, manganese Mn: 1.10-1.50, niobium Nb: 0.01-0.1, vanadium V: 0.01-0.1, titanium Ti: 0.006-0.03, chromium Cr: 0.40-0.70, nickel Ni: 0.30-0.40, copper Cu: 0.25-0.50, molybdenum Mo: not more than 0.20, nitrogen N: not more than 0.008.

Titanium microalloying is an element of denisty of 09CUPCRNI-B 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 denisty of 09CUPCRNI-B 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.

Vanadium is a weak deoxidizer. Adding vanadium into denisty of 09CUPCRNI-B steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

According to foreign media reports, despite the impact of the coronavirus epidemic, most German screw denisty of 09CUPCRNI-B steel producers still maintain a good level of production. This is in sharp contrast to the situation in other European countries and Germany's domestic steel mills, which are suffering from a slowdown due to the spread of the epidemic. Lotter kummatt Stahl, a local distributor, told customers on its website: "there is no reason at present to believe that German steel mills such as Riva and ferralpi are no longer able to serve the denisty of 09CUPCRNI-B market due to the impact of the closure of local steel mills in Italy.
