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

P235GH bụ paịpụ ígwè Fihekin na alloy nke na-arụ ọrụ nke ọma n'okpomọkụ, nke bụ ígwè e ji arụ ọrụ nke ọma n'okpomọkụ dị elu nke ndị Germany. P235GH, EN10216-2 paịpụ ígwè na-enweghị nrụgide kwekọrọ na ọkọlọtọ mba nke 20G, 20MnG (paịpụ ígwè na-enweghị nrụgide nke GB 5310-2008 nke na-enweghị nrụgide).

A na-agbazi paịpụ ígwè P235GH nke na-enweghị ntụpọ n'ime ọkụ eletrik na ihe ntụgharị oxygen. Maka ihe dị mkpa, ọ na-eji nchacha ihe dị n'èzí ọkụ, ịgbaze ọkụ induction ma ọ bụ ịgbaze ọkụ okpukpu abụọ, ịgbaze ọkụ electroslag ma ọ bụ ọgwụgwọ vacuum, na ọgwụgwọ okpomọkụ.

P235GH, EN10216-2 paịpụ ígwè na-enweghị nrụgide dabara adaba maka imepụta arịa nrụgide na akụrụngwa. Ma e jiri ya tụnyere ígwè nkịtị, ígwè alloy P235GH nwere ike na ike dị elu, arụmọrụ ịgbado oyi na arụmọrụ ịgbado ọkụ, njirimara kemịkalụ, ndakọrịta bio, njirimara anụ ahụ na arụmọrụ usoro.

Njirimara igwe nke paịpụ ígwè alloy P235GH: ike nrụgide σb350~480 MPa; ike mmepụta σs≥215 MPa; ogologo δ5≥ 25%; ike nnabata mmetụta Akv≥47 J; Ike siri ike Brinell ≤105~140 HB100

Ihe mejupụtara kemịkalụ (nkezi oke, %) nke paịpụ ígwè alloy P235GH: ≤0.16 Si; 0.60~1.20 Mn; ≤0.025 Cr; ≤0.30 Ni; ≤0.30 Cu; ≤0.08 Mo; ≤0.02 V; ≤0.02 Nb; ≤0.012 N; P; ≤0.010 S; ≤0.30, ≤0.020 Al; C; ≤0.35, ≤0.03 Ti.
