Q355GNH hlau

Cov khoom siv tseem ceeb yog elasticity, plasticity, nruj, aging rhiab heev, lub zog, hardness, cuam tshuam toughness, qaug zog thiab tawg toughness.
Elasticity: Cov khoom siv hlau deforms thaum nws raug rau sab nraud quab yuam. Thaum lub zog sab nraud raug tshem tawm, nws tuaj yeem rov qab tau nws qhov qub.

Cov specifications:
Thickness: 3mm-150mm
Dav: 30mm-4000mm
Ntev: 1000mm-12000mm
Txuj: ASTM EN10025 JIS GB
