Q235C ígwè efere

Q235B ígwè efere bụ ụdị obere carbon ígwè. Standardkpụrụ mba GB/T 700-2006 "Carbon Structural Steel" nwere nkọwa doro anya. Q235B bụ otu n'ime ngwaahịa igwe anaghị agba nchara na China. Ọ dị ọnụ ala ma nwee ike iji ya mee ihe n'ọtụtụ ngwaahịa na-adịghị achọ ịrụ ọrụ dị elu.

Usoro:
(1) Ihe mejupụtara ya bụ nọmba Q + + akara ọkwa ogo + akara deoxidation. A na-edobe nọmba nchara ya na "Q" iji nọchite anya ebe mkpụrụ nke igwe, na ọnụọgụ ndị a na-anọchi anya uru mkpụrụ mkpụrụ na MPa. Ọmụmaatụ, Q235 na-anọchi anya carbon structural ígwè nwere mkpụrụ mkpụrụ (σs) nke 235 MPa.
(2) Ọ bụrụ na ọ dị mkpa, akara ngosi nke ogo ogo na usoro deoxidation nwere ike igosi mgbe ọnụọgụ ígwè gasịrị. Akara ọkwa ogo bụ A, B, C, D. usoro deoxidation akara: F na-anọchi anya nchara esi; b Na-anọchite anya igwe na-egbu egbu; Z na-anọchi anya ígwè e gburu; TZ pụtara Steel egbu egbu pụrụ iche. Igwe egburu egbu nwere ike ọ gaghị enwe akara nrịbama, ya bụ, ma Z na TZ nwere ike ịhapụ enweghị akara. Dị ka ọmụmaatụ, Q235-AF na-anọchi anya klaasị A esi nchara.
(3) Carbon steel nwere ebumnuche pụrụ iche, dị ka akwa akwa akwa, ụgbọ mmiri ụgbọ mmiri, wdg, na-agbaso usoro okwu nke carbon structural steel, mana na-agbakwunye akwụkwọ ozi na-egosi ebumnuche na njedebe nke nọmba igwe.

Q235B nwere ụfọdụ elongation, ike, ezigbo ike na nkedo, ma dị mfe stampụ na weld. A na-ejikarị ya eme ihe n'ịrụpụta akụkụ igwe n'ozuzu. A na-ejikarị ya iji weld structural akụkụ na elu àgwà chọrọ na owuwu na akwa engineering.

AB na-akọwa ọdịiche dị n'etiti Q235A na Q235B
: The ígwè niile bụ carbon ígwè. Na ọkọlọtọ mba GB700-88, ihe dị iche n'etiti Q235A na Q235B bụ tumadi na carbon ọdịnaya nke ígwè. Ọdịnaya carbon nke ihe Q235A bụ 0.14-0.22%;
