C90S 1.1217 High Carbon Spring Steel Strip Delivery condition
Cold rolled narrow steel strip covered by EN10132-4 shall be supplied in one of the following delivery conditions:
-annealed or annealed and skin passed(+A or +LC);
-quenched and tempered(+QT).
NOTE The delivery condition-annealed to achieve spheroidized carbides(+AC)-may be agreed. In such cases, limits on spheroidization and mechanical properties may also be agreed at the time of enquiry and order.
C90S 1.1217 High Carbon Spring Steel Strip Surface finish
The surface finish of cold rolled narrow steel strip shall be bright as produced by rolling and annealing in a controlled atmosphere.
The surface finishes of quenched and tempered cold rolled strip are as follows:
1 grey/blue oxide finish:unpolished;
2 brigth tempered:unpolished
3 polished: obtained by fine grinding, abrasive brushing or other processes;
4 polished and coloured:blue or yellow colour obtained by oxidization by heat treatment.
High carbon steel is an ideal material for custom flat springs, custom clips, and custom sheet metal stampings. High Carbon Steel Strips combines ease of fabrication with good strength and surface finish, is valued for its strength properties and operates at significantly higher levels than the mild steel grades. High carbon steel strip can be finished to meet the needs of a wide range of products. Where tensile strength and hardness are required, High Carbon steels are the material of choice. High Carbon Steel Strips Grades : C60, C65, C70, C75, C85, HC-14, En 42 J, C-98, C-100, C-124, HC21 etc. We offer spring steel strip in various shapes and sizes according to your final uses. These have excellent hardens property and high yield strength. Clients can avail these at competitive prices.
Spring steel strip is used to build springs for a great variety of purposes. Below especially the cold rolled (carbon as well as stainless) spring steel strip will be described in detail. The most common production width of spring steel strip is about 300 mm (11.811 inches). As a matter of course spring steel strip can be slit or cut to length (sheets). We supply a very wide range of high carbon and alloys, covering the most stringent industrial requirements. We have also developed a unique know-how in the design of custom solutions for special applications.
C90s, 1.1217, 95cr1, 1.2018 - low-alloy spring steel with high carbon content for heat treatment - oil hardening according to en 10132-4 and en 10270-1. Spring construction steel for oil hardening for springs and working periodically springs with small dimensions.
Provided in the form of a spring tapes - C90S is characterized by high abrasion resistance and high strength.In addition to the use for springs, it is also designed for wood and stone saws, knives and machine scissors, spring washers, cutting elements and cutting tools. After the treatment shows the structure of tempered martensite. During heat treatment, a protective atmosphere should be used to avoid decarburization and oxidation of the material.C90S steel has a higher carbon content than C67S, C55S and C75S.
