Marking steels

Gịnị mere m mkpa na-akanye na ọtụtụ ihe - gịnị ka ọ pụtara? Mbụ niile, ọ na-kpatara a koodu na-egosiputa Njirimara nke ngwongwo. N'ihi na onye ọ bụla ngwaahịa na-etinyere gị koodu. Ọ bụla ụlọ ọrụ (chemical, akpakanamde, arọ, ìhè) chọrọ marking ma ọ bụ barcodes.

Industrial marking (eg marking nke steels na alloys) na-enyere aka qualitatively ịrụ n'ihu ọrụ n'ebe ahụ, ebe a ga-mechara nke a ngwaahịa. Ka e were ya na-akanye ọkpọkọ ga-ekwe ka na-ewu ụlọ na-emepụta na-agba ọsọ mmiri nri na, n'aka nke ya, adịghị eduga na-atụghị anya ihe mberede na anwụrụ izu n'okpuru ibu.

Mkpọrọgwụ labeling aghọwo indelible agba. Ndị na-esonụ na nkenke awade nhazi ọkwa na labeling nke steels. Ya mere ...

Na ot ígwè (nkịtị quality) etinyere cm akwụkwọ ozi na nọmba. Ọ anya dị ka ST3, St2, St1, St0. Steel quality (carbon) na-akara na nọmba abụọ, ọnụ ọgụgụ na-egosi na ọdịnaya nke carbon percentages (hundredths nke a) .. 40, 25, 10, 08, wdg, na akwụkwọ ozi T na-akanye na-egosi ubara ọdịnaya ígwè nke manganese (18g , 14D, wdg)

Steel submachine akara akpa leta nke Russian mkpụrụ okwu A (A30, A12, wdg). On carbon ígwè ngwá ọrụ, akwụkwọ ozi Y (U12, U10, U8, ebe nọmba egosi na ọdịnaya nke ígwè na 10 si of a percent).

Stampụ Alloy steels nwere akwụkwọ ozi na-egosi na mmiri na-eme ka a akpan akpan ígwè, na-akọwa ha nkezi ọdịnaya nke nitrogen na-họpụtara dị ka A, aluminum - Y, vanadium - F, Bor - P, igwe - D, cobalt - K, sịlịkọn - C manganese - G, molybdenum - M, ọla kọpa - D, nickel - N, selenium - B, carbon - Y, edebata - C, Chrome - X, site - P, zirconium - TS

The mbụ nọmba egosi na ọdịnaya nke nchara akụrụngwa akpọ carbon na hundredths nke a kọwaa nke bughi steels na iri - maka igwe anaghị steels na ngwá ọrụ. Mgbe akwụkwọ ozi ẹkedọhọde alloying mmewere. Site akwụkwọ ozi sochiri nọmba egosi na nkezi ọdịnaya nke a mmewere na nkeji (integers). Ọ bụrụ na ọdịnaya nke alloying ọcha bụ ihe na-erughị iri na ise percent, na digits mgbe kwesịrị ekwesị akwụkwọ ozi na-adịghị depụtara. The ọnụnọ na njedebe nke akwụkwọ ozi A na-egosi na elu àgwà nke ígwè. The akwụkwọ ozi W - pụrụ iche iche àgwà (karịsịa anaghị agba nchara).

Nkịtị ígwè quality: BSt0, VSt0, St0 (agba-acha uhie uhie, ma ọ bụ akwụkwọ ndụ akwụkwọ ndụ); VSt1kp, St1 (edo edo), BSt3, St3, VST3kp, BSt3kp, VSt3 (red na agba) BSt4, St4, BSt4kp, VSt4kp, VSt4 (nwa) St5 na VSt5 (ndụ ndụ na agba) na n'ikpeazụ St6 (Agba-acha anụnụ anụnụ ).

Carbon Steel quality: 20, 15, 10, 08 (na-acha ọcha na agba); 40, 35, 30, 25 (na-acha ọcha, odo); 60, 55, 50, 45 (na-acha ọcha, aja aja).

Structural Steel Alloy: chromium (ndụ ndụ na agba, odo); Chrome (na agba akwụkwọ ndụ akwụkwọ ndụ, nwa); Chrome (ma green ma ọ bụ acha odo odo); Chrome Manganese (nwa, acha anụnụ anụnụ); manganese (aja aja ma ọ bụ-acha anụnụ anụnụ); hromokremnemargantsovaya (-acha anụnụ anụnụ, red); hromoalyuminievaya (aluminum); hromonikelemolibdenovaya (odo odo ma ọ bụ nwa).

Corrosion na-eguzogide ígwè: CrNi (acha ọbara ọbara, ma ọ bụ aluminum); chrome; chromium (aluminum ma ọ bụ nwa), hromotitanovaya (odo ma ọ bụ aluminum); hromonikeletitanovaya (acha anụnụ anụnụ, aluminum); hromonikelekremnistaya (ndụ ndụ, aluminum); hromomargantsenikelevaya (Agba aluminum ma ọ bụ aja aja), hromonikeleniobievaya (ọcha, ma ọ bụ aluminum) na hromonikelemolibdenotitanovaya ígwè (violet agba, aluminum).

Akwa-agba ígwè, họpụtara dị ka P18 (ọla ma ọ bụ red) na P9 (ọla agba).

Firm alloys sintered. N'ọnọdụ dị otú alloys ndị na-esonụ markings etinyere steels: VK2 (ọcha na nwa straipu); VK3-M (oroma warara na nwa), VK4 (oroma); VK6 (anụnụ anụnụ na agba); VK6-B (violet); VK6-M (ọcha warara on a-acha anụnụ anụnụ); BK8 (red); BK8-B (-acha anụnụ anụnụ straipu on a red); VK15 (ọcha); T30K4 (-acha anụnụ anụnụ); T15K6 (ndụ ndụ na agba).

Eji ihe ndị a dị mfe iwu, pụtara mfe iji chọpụta ihe ndị mejupụtara na Njirimara nke ígwè. Akara ma mepụtara na USSR, ma ka a pụrụ isi kwuo taa na CIS na Russia.
