420 stainless hlau yeeb nkab kho cua sov
420 stainless hlau yog high-carbon martensitic stainless hlau uas muaj chromium. Nws yog lub npe hu rau nws zoo heev corrosion kuj thiab siab hardness. Lub npe "420" yog hais txog cov ntsiab lus tshwj xeeb ntawm cov hlau, uas suav nrog kwv yees li 0. qee zaum molybdenum.

Nov yog cov lus piav qhia ntxaws ntxaws ntawm cov kauj ruam kho cua sov rau 420 stainless hlau:
1, Annealing: Thawj kauj ruam yog annealing, uas yuav tsum tau cua sov lub 420 stainless hlau yeeb nkab mus rau qhov kub thiab txias, feem ntau nyob ib ncig ntawm 820-900 degree (1508-1652 degree F), thiab ces maj mam txias nws nyob rau hauv ib tug tswj hwm. . Cov txheej txheem no txo cov kev ntxhov siab sab hauv, txhim kho ductility, thiab tso cai rau kev sib xws hauv cov kauj ruam tom ntej kev kho cua sov.
2, Hardening: Tom qab annealing, cov yeeb nkab yog rhuab mus rau qhov kub tseem ceeb ntawm 980-1065 degree ({2}} degree F) thiab tuav ntawm qhov kub ntawm lub sijhawm tshwj xeeb. Qhov ntsuas kub no ua kom cov hlau tsis muaj hlau hloov pauv los ntawm nws cov theem austenitic mus rau theem martensitic, uas ua rau muaj zog ntxiv.
3, Quenching: Thaum cov yeeb nkab ncav cuag qhov xav tau hardening kub, nws yog txias txias los ntawm immersing nws nyob rau hauv ib tug quenching nruab nrab, xws li roj, dej, los yog huab cua, nyob ntawm seb qhov xav tau hardness thiab mechanical zog. quenching sai "freezes" steel lub microstructure, xauv rau hauv cov qauv martensitic thiab ua tiav siab hardness.
4, Tempering: Cov yeeb nkab quenched yog tom qab ntawd rov ua kom sov rau qhov kub ib txwm nyob nruab nrab ntawm 200-300 degree (392-572 degree F) thiab tuav ntawm qhov kub ntawm lub sijhawm tshwj xeeb. Tempering pab txo cov brittleness los ntawm cov txheej txheem hardening thiab ntxiv txhim khu cov khoom toughness, ductility, thiab lub zog. Qhov tshwj xeeb tempering kub thiab lub sij hawm nyob ntawm seb qhov xav tau sib npaug ntawm hardness thiab toughness xav tau rau daim ntawv thov.
