Voorverwarming:<\/strong> bij het oplassen van gelegeerd staal, wordt aanbevolen een voorverwarming toe te passen van 150\u00b0C tot maximaal 250\u00b0C.<\/li>\n
Beschermgas:<\/strong> gebruik Argon met 1 tot 3% O2 (M12) of Argon\/CO2 (M21). CO2-houdende gassen verbeteren de hardheid van de neersmelt.<\/li>\n
Warmtebehandeling<\/strong>\n
\n
Zachtgloeien: 750\u2013800\u00b0C in de oven.<\/li>\n
Harden: 1000\u20131050\u00b0C, met olie of lucht.<\/li>\n
Ontlaten: 650\u2013750\u00b0C voor een gecontroleerde harding.<\/li>\n<\/ul>\n<\/li>\n
Lastoorts:<\/strong> gebruik een teflon spiraal in de lastoorts voor een stabiele boog en een betrouwbare lasverbinding.<\/li>\n<\/ul>\n<\/div> <\/div>\n <\/div>\n
Deze roestvaststalen draad biedt uitstekende sleetweerstand bij metaal-metaalcontact en abrasie door klei of vergelijkbare materialen. Dankzij de hoge hardheid, die goed behouden blijft bij temperaturen tot 500\u00b0C, is de draad bijzonder duurzaam. De neersmelt is zeer goed polijstbaar, wat resulteert in een sleetweerstand die zelfs hoger is dan die van draden met een hogere hardheid. Bovendien biedt de draad uitstekende corrosieweerstand tegen water, damp, zeewater en verdunde organische zuren. Hij is tevens oxidatiebestendig tot 900\u00b0C.<\/p>\n","protected":false},"featured_media":1481,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":true},"product_brand":[],"product_cat":[3825,196,3978],"product_tag":[],"class_list":["post-26694","product","type-product","status-publish","has-post-thumbnail","product_cat-lasdraad","product_cat-lastoevoegmaterialen","product_cat-overige-materialen","pa_lasproces-mig-mag","pa_merk-lastifil","pa_te-lassen-materiaal-hardoplassingen","first","instock","purchasable","product-type-simple"],"acf":[],"yoast_head":"\n
