Nchọpụta ntụpọ ASTM-SA516Gr60Z35 Steel Plate

Nchọpụta ntụpọ ASTM-SA516Gr60Z35 igwe anaghị agba nchara:
1. SA516Gr60 ọkọlọtọ ọkọlọtọ: American ASTM, ASME ụkpụrụ
2. SA516Gr60 bụ nke obere okpomọkụ mgbali arịa na carbon ígwè efere
3. Chemical mejupụtara nke SA516Gr60
C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45.
4. Mechanical Njirimara nke SA516Gr60
SA516Gr60 ike tensile nke 70 puku pound/square inch, isi ihe dị n'ime ya bụ njikwa C Mn Si ps na-ekpebi arụmọrụ ya.Ihe nchọta ndị ọzọ dị obere.Asme Standard nkọwapụta maka carbon ígwè efere maka ọkara na obere okpomọkụ arịa.
5. Ọkwa nnyefe nke SA516Gr60
A na-enyekarị efere ígwè SA516Gr60 n'ụdị mpịakọta, a pụkwara ịhazi efere ígwè ma ọ bụ nkwụsị nchekasị, ma ọ bụ normalize gbakwunyere usoro enyemaka nrụgide.
SA516Gr60 ọkpụrụkpụ>40mm ígwè efere kwesịrị normalized.
Ọ gwụla ma onye na-achọ ya akọwapụtaghị ya, ọkpụrụkpụ nke efere nchara ≤1.5in, (40mm), mgbe enwere ihe siri ike chọrọ, kwesịrị ịhazi ya.
