Chronifer Special KL, Chrome-Nickel-Molybdenium-Steel, not hardenable. Austenitic stainless steel with improved machining properties due to the content of Sulfur (S). This high quality steel is mainly designed for watch parts. Its corrosion resistance is higher than the standard Aisi 303. The Chronifer Special KL is a good compromise between machinability and corrosion resistance. Compared to our Aisi 316L Decolletage, it has less copper content (max. 0.6% considered as traces).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Brief description Klein designation: Chronifer Special KL Class of metals: Free machining martensitic stainless steel with S addition Standard  [&#8230;]<\/p>\n","protected":false},"featured_media":61217,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false},"product_brand":[],"product_cat":[847,1036,869,807,845,863],"product_tag":[],"class_list":{"0":"post-157067","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-austenitic","7":"product_cat-aviation","8":"product_cat-corrosion-resistant","9":"product_cat-free-cutting-steel","10":"product_cat-stainless-steel","11":"product_cat-watchmaking-alloys","12":"pa_ausfuehrung-6-kant","13":"pa_ausfuehrung-drawn","14":"pa_ausfuehrung-ground","15":"pa_ausfuehrung-hex","16":"pa_ausfuehrung-2-bars-2m","17":"pa_ausfuehrung-2-bars-3m","18":"pa_ausfuehrung-2-in-spools","19":"pa_ausfuehrung-2-staebe-2m","20":"pa_durchmesser-0-600","21":"pa_durchmesser-0-700","22":"pa_durchmesser-0-800","23":"pa_durchmesser-0-900","24":"pa_durchmesser-1-000","25":"pa_durchmesser-1-100","26":"pa_durchmesser-1-200","27":"pa_durchmesser-1-300","28":"pa_durchmesser-1-400","29":"pa_durchmesser-1-500","30":"pa_durchmesser-1-600","31":"pa_durchmesser-1-700","32":"pa_durchmesser-1-800","33":"pa_durchmesser-1-900","34":"pa_durchmesser-10-000","35":"pa_durchmesser-10-500","36":"pa_durchmesser-11-000","37":"pa_durchmesser-11-500","38":"pa_durchmesser-12-000","39":"pa_durchmesser-13-000","40":"pa_durchmesser-14-000","41":"pa_durchmesser-15-000","42":"pa_durchmesser-16-000","43":"pa_durchmesser-17-000","44":"pa_durchmesser-18-000","45":"pa_durchmesser-19-000","46":"pa_durchmesser-2-000","47":"pa_durchmesser-2-100","48":"pa_durchmesser-2-200","49":"pa_durchmesser-2-500","50":"pa_durchmesser-2-600","51":"pa_durchmesser-2-700","52":"pa_durchmesser-2-800","53":"pa_durchmesser-20-000","54":"pa_durchmesser-3-000","55":"pa_durchmesser-3-200","56":"pa_durchmesser-3-500","57":"pa_durchmesser-3-600","58":"pa_durchmesser-4-000","59":"pa_durchmesser-4-200","60":"pa_durchmesser-4-300","61":"pa_durchmesser-4-500","62":"pa_durchmesser-4-800","63":"pa_durchmesser-5-000","64":"pa_durchmesser-5-500","65":"pa_durchmesser-6-000","66":"pa_durchmesser-6-200","67":"pa_durchmesser-6-500","68":"pa_durchmesser-7-000","69":"pa_durchmesser-7-500","70":"pa_durchmesser-8-000","71":"pa_durchmesser-8-500","72":"pa_durchmesser-9-000","73":"pa_durchmesser-9-500","74":"pa_toleranz-fg-6-en","75":"pa_toleranz-fg-6","76":"pa_toleranz-fg-7-en","77":"pa_toleranz-fg-8-en","78":"pa_toleranz-h-6-en","79":"pa_toleranz-h-7-en","80":"pa_toleranz-h-8-en","81":"pa_toleranz-h-9-en","83":"first","84":"instock","85":"purchasable","86":"product-type-variable"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
