Abstract

The invention discloses a formula of a special stainless steel for a crane cable coaster and a preparation method thereof. The formula of a special stainless steel for a crane cable coaster is composed of the following components in percentage by weight: less than or equal to 0.02% of C, less than or equal to 0.75% of Si, less than or equal to 0.05% of Mn, less than or equal to 0.01% of S, less than or equal to 0.02% of P, 21.00-23.00% of Cr, 8.00-9. 50% of Ni, 0.30-0.45% of Cu, less than or equal to 0.03% of N, less than or equal to 0.04% of Ti, and the balance of Fe and unavoidable impurities, with 2C being less than or equal to Ti. The formula of a special stainless steel for a crane cable coaster has the effect of reducing the rusting probability of the crane cable coaster.

Description

Technical field [0001] The invention relates to crane equipment, in particular to a stainless steel formula specially used for crane cable pulleys and a preparation method thereof. Background technique [0002] Cables on cranes are generally carried by cable trolleys and driven to travel. The cable trolley is exposed and is eroded by rain water all year round. The bearing of the cable trolley roller is easy to rust, so that the cable trolley roller cannot rotate on the track but hardly rubs. Under the condition of strong pulling, the cable trolley will be pulled down or The cable is disconnected. To solve this problem in the prior art, cable pulleys made of stainless steel are generally used to reduce the possibility of rust. [0003] The application publication number is CN103131961A, and the application publication date is June 5, 2013. The Chinese patent discloses a corrosion-resistant stainless steel plate and its preparation method and application. It is composed of the foll...
