To further improve this, the parts must be well polished. Due to its low sulfur and carbon content, this grade is more corrosion-resistant than 1.4034 or 1.4035. However, the hardness is lower than 1.4028 or 1.4034. The use of this material is versatile, covering applications in industries such as medicine or dental for undemanding parts.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Brief description Designation Klein: CHRONIFER M-4021 Class of metals: Hardenable martensitic stainless steel Material number: 1.4021 Standard EN: X  [&#8230;]<\/p>\n","protected":false},"featured_media":61364,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false},"product_brand":[],"product_cat":[839,851,837,845],"product_tag":[],"class_list":{"0":"post-158684","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-instruments","7":"product_cat-martensitic","8":"product_cat-medical-steel","9":"product_cat-stainless-steel","10":"pa_ausfuehrung-drawn","11":"pa_ausfuehrung-geschliffen","12":"pa_ausfuehrung-ground","13":"pa_ausfuehrung-2-bars-3m","14":"pa_ausfuehrung-2-in-spools","15":"pa_ausfuehrung-2-ring","16":"pa_durchmesser-4-752","17":"pa_durchmesser-1-000","18":"pa_durchmesser-1-100","19":"pa_durchmesser-1-200","20":"pa_durchmesser-1-500","21":"pa_durchmesser-1-600","22":"pa_durchmesser-1-700","23":"pa_durchmesser-1-800","24":"pa_durchmesser-10-000","25":"pa_durchmesser-11-000","26":"pa_durchmesser-12-000","27":"pa_durchmesser-12-700","28":"pa_durchmesser-13-000","29":"pa_durchmesser-14-000","30":"pa_durchmesser-15-000","31":"pa_durchmesser-15-875","32":"pa_durchmesser-16-000","33":"pa_durchmesser-17-000","34":"pa_durchmesser-18-000","35":"pa_durchmesser-19-050","36":"pa_durchmesser-2-000","37":"pa_durchmesser-2-100","38":"pa_durchmesser-2-300","39":"pa_durchmesser-2-350","40":"pa_durchmesser-2-500","41":"pa_durchmesser-2-700","42":"pa_durchmesser-2-800","43":"pa_durchmesser-20-000","44":"pa_durchmesser-22-000","45":"pa_durchmesser-23-000","46":"pa_durchmesser-24-000","47":"pa_durchmesser-25-000","48":"pa_durchmesser-25-400","49":"pa_durchmesser-27-000","50":"pa_durchmesser-3-000","51":"pa_durchmesser-3-200","52":"pa_durchmesser-3-500","53":"pa_durchmesser-4-000","54":"pa_durchmesser-4-100","55":"pa_durchmesser-4-500","56":"pa_durchmesser-5-000","57":"pa_durchmesser-5-100","58":"pa_durchmesser-5-400","59":"pa_durchmesser-5-500","60":"pa_durchmesser-6-000","61":"pa_durchmesser-6-100","62":"pa_durchmesser-6-350","63":"pa_durchmesser-6-500","64":"pa_durchmesser-7-000","65":"pa_durchmesser-8-000","66":"pa_durchmesser-8-100","67":"pa_durchmesser-9-000","68":"pa_toleranz-fg-7","69":"pa_toleranz-fg-7-en","70":"pa_toleranz-h-6-en","71":"pa_toleranz-h-7-en","72":"pa_toleranz-h-8-en","73":"pa_toleranz-spec-en","75":"first","76":"instock","77":"purchasable","78":"product-type-variable"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
