Nrog rau txoj kev loj hlob sai ntawm lub zog tshiab tsheb (NEV) kev lag luam, SPCC txias- dov steel, galvanized steel, thiab stainless hlau yog cov khoom siv feem ntau rau NEV stamping qhov chaw. Kab lus no luv luv piv lawv cov khoom tseem ceeb, kev ua tau zoo, daim ntawv thov scenarios, thiab cov yam ntxwv tseem ceeb los muab cov lus qhia ceev rau kev xaiv cov khoom.
Txheej txheem cej luam ntawm Peb Cov Khoom
SPCC Txias -Rolled Steel: Ib qho yooj yim kev lag luam txias-rolled carbon steel nrog cov ntsiab lus carbon tsawg, du nto, thiab siab qhov tseeb, haum rau stamping qhov chaw uas tsis tshua muaj corrosion kuj.
Galvanized hlau: Hlau ntawv coated nrog zinc, inheriting lub formability ntawm lub hauv paus steel thiab tau txais zoo corrosion kuj. Hom hom: electro-galvanized (SECC) thiab kub-dip galvanized (SGCC).
Stainless hlau: Feem ntau SUS304 / SUS316 austenitic stainless hlau, nrog zoo corrosion kuj thiab siab zog, tab sis tus nqi siab dua thiab kev ua haujlwm nyuaj.
Core Performance Comparison
Mechanical Properties
SPCC: Tsawg zog (lub zog tensile 300-400MPa), siab ductility thiab formability, tsis haum rau siab - load-bearing qhov chaw.
Galvanized hlau: Zoo ib yam li SPCC (lub zog tensile 320-420MPa), zoo formability; SGCC muaj cov txheej zinc tuab dua tab sis qis dua ductility dua li SECC.
Stainless hlau: Siab zog (SUS304: 520-720MPa), zoo toughness, me ntsis tsis zoo ductility, yuav tsum tau ntau dua stamping technology.
Corrosion Resistance
SPCC: Ua tsis taus pa, yooj yim rau xeb, yuav tsum tau tshaj tawm -stamping nto kho (txhaj tshuaj, electroplating).
Galvanized hlau: 3-5 zaug zoo dua li SPCC, zinc txheej muab kev tiv thaiv, haum rau cov chaw sab nraum zoov / ntub dej.
Stainless hlau: Qhov zoo tshaj plaws, tsis muaj tshuaj tiv thaiv- xeb yuav tsum tau kho, haum rau qhov chaw hnyav (ntev ntug dej hiav txwv, siab- cov roj teeb av noo).
Stamping Processability
SPCC: Qhov zoo tshaj plaws, du nto, tsis tshua muaj pwm hnav, kev tsim nyog tus nqi, tsim nyog rau ntau lawm.
Galvanized hlau: Zoo, zoo ib yam li SPCC; Nco ntsoov SGCC lub ductility nyob rau hauv complex stamping.
Stainless hlau: Ua tsis taus pa, ua rau brittleness thaum lub sij hawm stamping, yuav tsum muaj kev siv tshuab thiab khoom siv.
Summary of Application Scenarios
🔵SPCC: Internal non{0}}corrosive stamping qhov chaw (xws li, lub cev muaj zog, cov khoom hauv chassis).
🔵 Galvanized Steel: Sab nraum zoov / chassis qhov chaw (xws li, roj teeb pob brackets, chassis tsau qhov chaw).
🔵Stainless Steel: High-corrosion, siab- lub zog qhov chaw (piv txwv li, roj teeb pob khoom sab hauv, ntug dej hiav txwv- thaj tsam NEV).
