Kedu ihe bụ P235GH? Kedu ihe ọ dabara na China?

P235GH bụ arụmọrụ dị elu nke Fihekin na ọkpọkọ ígwè alloy, nke bụ nchara nchara dị elu nke German. P235GH, EN10216-2 mgbali enweghị nkebi ígwè ọkpọkọ kwekọrọ na mba ọkọlọtọ 20G, 20MnG (GB 5310-2008 elu-nrụgide ji esi mmiri ọkụ enweghị nkebi ígwè ọkpọkọ).

P235GH alloy steel pipe pipe na-agbazekarị n'ọkụ ọkụ eletrik na ihe ntụgharị ikuku oxygen n'elu. Maka ihe achọrọ dị elu, ọ na-anabata nnụcha n'èzí ọkụ, oghere induction ọkụ na-agbaze ma ọ bụ ịgbaze oghere okpukpu abụọ, mgbaze electroslag ma ọ bụ ọgwụgwọ agụụ, na ọgwụgwọ okpomọkụ.

P235GH, EN10216-2 ọkpọkọ igwe anaghị agba nchara dị mma maka imepụta arịa nrụgide na akụrụngwa akụrụngwa. E jiri ya tụnyere ígwè nkịtị, P235GH alloy steel nwere ike dị elu na ike siri ike, arụmọrụ na-ehulata oyi na ịrụ ọrụ ịgbado ọkụ, akụrụngwa kemịkalụ, biocompatibility, akụrụngwa anụ ahụ na arụmọrụ usoro.
