Kev piav qhia
Cov khoom siv raw ntawm Cov Hlau Stainless Investment Casting Parts yog 17-4PH stainless hlau . 17-4PH yog cov nag lossis daus hardening martensitic stainless hlau uas muaj tooj liab, niobium thiab columbium. Cov khoom muaj lub zog siab, hardness thiab corrosion kuj. Tom qab kev kho cua sov, lub tshuab ua haujlwm ntawm cov khoom zoo tshaj plaws, thiab lub zog compressive tuaj yeem ncav cuag 1100-1300 Mpa (160-190 ksi). Vim nws cov ntsiab lus tsis tshua muaj carbon, nws muaj kev ua haujlwm zoo dua, kev tiv thaiv corrosion thiab weldability dua li martensitic stainless hlau xws li Cr13, 9Cr18 thiab 1Cr17Ni2. Feem ntau, nws muaj tib yam corrosion kuj zoo li 304 stainless hlau.
Nta
1. Cov Hlau Stainless Investment Casting Parts muaj qhov zoo corrosion kuj rau cua, dilute acid los yog ntsev, thiab corrosion kuj yog tib yam li 304 thiab 430.
2. Lawv muaj kev ua haujlwm zoo attenuation, muaj zog corrosion qaug zog tsis kam thiab dej tsis kam.
3. Tom qab kev kho cua sov ntawm 17-4PH, lub tshuab ua haujlwm ntawm cov khoom yog zoo meej dua, thiab lub zog compressive tuaj yeem siab li 1100-1300 MPa.
4. Nws yog dav siv hauv kev lag luam petrochemical, kev lag luam ua zaub mov, kev lag luam ntawv thiab kev lag luam aerospace.
