25Cr2MoVA Hardware Tool Steel Bar
25Cr2MoVA round steel yog nruab nrab carbon kub-resistant steel. Siab zog thiab toughness. Thaum qhov kub thiab txias qis dua 500 degree, qhov kub siab ua haujlwm zoo, tsis muaj qhov cuam tshuam ntawm thermal brittleness, permeability zoo, lub machinability tau txais, qhov txias deformation plasticity yog nruab nrab, thiab weldability tsis zoo. Feem ntau nws tuaj yeem siv rau hauv lub xeev quenched thiab tempered, los yog tom qab normalizing thiab high-temperature tempering. Nws muaj kev tiv thaiv zoo rau intergranular corrosion, zoo heev corrosion kuj thiab txias ua hauj lwm stamping kev ua tau zoo, muaj zog corrosion kuj rau oxidizing acids (xws li nitric acid), thiab tej yam kuj rau alkaline daws thiab feem ntau organic thiab inorganic acids. Corrosion kuj.
