It replaces solid bar wherever the finished part has to be hollow anyway, saving drilling and boring time, material and tooling.<\/p><h3>Typical applications<\/h3><ul><li>bearing, guide and spacer bushes,<\/li><li>rings, flanges and sealing components,<\/li><li>valve bodies, fittings and hydraulic parts,<\/li><li>hollow shafts and machine parts for the food, chemical and marine industries.<\/li><\/ul><h3>Standards and choosing a size<\/h3><p>Hollow bars for machining are covered by EN 10294-2, and seamless stainless steel tubes by EN 10216-5. When choosing a size, allow for machining stock: the outside diameter of the hollow bar should be slightly larger, and the inside diameter slightly smaller, than those of the finished part.<\/p><h3>Why hollow bar instead of solid bar?<\/h3><p>When machining solid bar, most of the material ends up as swarf. A hollow bar with the right inside diameter shortens machining time, reduces tool wear and lowers the cost per part \u2013 especially for large diameters and more expensive acid-resistant grades.<\/p>","link":"https:\/\/stalesia.com\/en\/stainless-steel-hollow-bars\/","name":"Stainless steel hollow bars","slug":"stainless-steel-hollow-bars","taxonomy":"product_cat","parent":0,"meta":[],"menu_order":0,"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Stainless steel hollow bars for machining<\/title>\n<meta name=\"description\" content=\"Seamless stainless and acid-resistant steel hollow bars for machining.
