4CR13 Jeklo<\/h3>

Jeklo 4Cr13 je marenzitni tip obarvanega jekla, ki ima po kaljenju ve\u010djo ro\u010dnost kot jeklo 30r13.Thesitel ima dobro mehansko procesno zmogljivost. Po toplotni obdelavi (kaljenju in popu\u0161\u010danju) ima dobro korozijsko odpornost, poliranje, visoko trdnost in odpornost proti obrabi.<\/p>

Toplotna obdelava jekla 4Cr13<\/h3>

1. \u017darjenje
750 do 800 \u00b0C pribli\u017eno 2 do 5 ur
Po\u010dasno nadzorovano hlajenje pri 10 do 20 \u00b0C na uro do pribli\u017eno 650 \u00b0C;
Nadaljnje hlajenje na zraku, max. 200 HB<\/p>

2. Kaljenje
1000 do 1050 \u00b0C
Temperaturo utrjevanja vzdr\u017eujte 15 do 30 minut.
Kaljenje v olju\/stisnjenem plinu\/vro\u010di kopeli
Razpolo\u017eljiva trdota: 53-56 HRC<\/p>

3. Kaljenje
Takoj po kaljenju po\u010dasi segrevajte do temperature popu\u0161\u010danja, odvisno od zahtevane trdote, do 180 do 300 \u00b0C.
1 ura na 20 mm: najmanj 2 uri<\/p>

Aplikacije<\/h3>

Jeklo 4Cr13 je primerno za jedra in votline injekcijskih kalupov z visokim ogledalom in visoko natan\u010dnostjo. Uporablja se tudi kot proti koroziji in obrabi odporni deli, kot so \u010drpalke za vro\u010de olje, plo\u0161\u010de ventilov, le\u017eaji ventilov, medicinska oprema, vzmeti itd.<\/p>

Tipi\u010dna uporaba:<\/h3>

Jeklo 4Cr13 je primerno za postopke elektri\u010dnega praznjenja in bru\u0161enja. Primerno je za izdelavo jeder in votlin kalupov za zelo natan\u010dne injekcijske kalupe z visoko zrcalno povr\u0161ino. Po toplotni obdelavi ima visoko trdoto in \u017eilavost. Uporablja se lahko tudi za \u0161tancanje dodatkov za kalupe, \u0161ablon itd., kjer so zahteve za vpenjanje na povr\u0161ino izdelka. Pripomo\u010dki in kalupi itd.; primerni za prizore z visoko temperaturno rjo in protikorozijsko za\u0161\u010dito.<\/p>

Civilna uporaba: lahko se uporablja za izdelavo namiznih in zunanjih no\u017eev.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"

Jeklo 4Cr13, martenzitno nerjavno jeklo, ima visoko trdnost, dobre lastnosti poliranja, odli\u010dno odpornost na korozijo in vro\u010do oksidacijo [1]. Zaradi teh odli\u010dnih lastnosti se lahko nerjavno jeklo 4Cr13 uporablja na ve\u010d pomembnih podro\u010djih, kot so natan\u010dni mehanizmi, konstrukcijska avtomobilska uporaba in petrokemi\u010dna industrija.<\/div>\n<\/div>","protected":false},"featured_media":1425,"comment_status":"closed","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"no-sidebar","site-content-layout":"","ast-site-content-layout":"full-width-container","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[22],"product_tag":[64],"class_list":["post-1424","product","type-product","status-publish","has-post-thumbnail","product_cat-mold-steel","product_tag-mold-steel","desktop-align-left","tablet-align-left","mobile-align-left","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/www.jycomat.com\/sl\/wp-json\/wp\/v2\/product\/1424","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.jycomat.com\/sl\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.jycomat.com\/sl\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.jycomat.com\/sl\/wp-json\/wp\/v2\/comments?post=1424"}],"version-history":[{"count":0,"href":"https:\/\/www.jycomat.com\/sl\/wp-json\/wp\/v2\/product\/1424\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.jycomat.com\/sl\/wp-json\/wp\/v2\/media\/1425"}],"wp:attachment":[{"href":"https:\/\/www.jycomat.com\/sl\/wp-json\/wp\/v2\/media?parent=1424"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.jycomat.com\/sl\/wp-json\/wp\/v2\/product_brand?post=1424"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.jycomat.com\/sl\/wp-json\/wp\/v2\/product_cat?post=1424"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.jycomat.com\/sl\/wp-json\/wp\/v2\/product_tag?post=1424"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
