Bochum Steel Works

What Bochum Steel Works does

Stahlwerke Bochum GmbH (SWB) is a German family-owned steel foundry that develops, manufactures, and supplies highly wear-resistant cast components for industrial processing equipment. Its core products are differentiated hardened shredder hammers (in which it claims world market leadership), wear parts for impact crushers, grinding media, and scrap shear blades. The company is headquartered in Bochum, Germany, where it operates the sole production facility — including induction furnaces, semi-automatic and hand molding shops (supporting castings up to 7,000 kg), individualized heat treatment, and computer-simulated casting technology. Its product portfolio draws on 37 alloy steel grades, and the proprietary differentiated hardening process — invented at SWB roughly 30 years ago — produces components with a hard outer wear surface and a tough core.

SWB's customers are primarily B2B industrial operators in three verticals: (1) steel and metal recycling (shredders, scrap shears, chip shredders), (2) construction waste recycling and mineral processing (horizontal and vertical impact crushers), and (3) cement manufacturing and mineral preparation (grinding media, briquetting press components). The company is DIN EN ISO 50001:2018 certified for energy management and produces exclusively from secondary raw materials (scrap steel), which it cites as preventing approximately 1.67 tonnes of CO2 per tonne of scrap used versus primary production.

The business model is hardware sales of customized, quote-priced components. SWB generates revenue through direct sales from its Bochum headquarters supported by a network of exclusive sales representatives and distributors covering North America, Europe, the Middle East, South America, and Asia. Approximately 75% of revenue is exported, with deliveries to more than 50 countries. Go-to-market combines enterprise field sales with event-driven demand generation at major industry trade shows (IFAT, steinexpo, recycling aktiv, Forum MIRO, BDSV, BIR). The company has reported cumulative production exceeding 1.33 million shredder hammers and 5.1 million slag plates, and has been continuously profitable since its 1989 spin-off from the Thyssen Group. Since 2006, it has been 100% family-owned under SWB Holding GmbH.

Broad incumbents

• Sandvik: Swedish multinational with mining and rock processing division that manufactures crushing equipment and wear parts. Significantly larger and broader portfolio; competes with SWB through its aftermarket wear-parts offering on Sandvik-branded machines.
• Metso: Finnish-headquartered global leader in mining, aggregates, and metals processing equipment with a substantial wear-parts aftermarket business. Larger, more diversified player that competes with SWB primarily through OEM-captive wear-parts offerings rather than direct casting.
• Terex: US-based diversified equipment manufacturer with crushing and screening product lines (Powerscreen, Finlay, EvoQuip). Indirect competitor through its aftermarket wear-parts business and OEMs that compete with SWB's customer base.
• FLSmidth: Danish-headquartered supplier of equipment and services to cement and mining industries, including wear components for crushers and mills. Overlaps with SWB in cement-industry grinding media and mineral processing wear applications.

Direct peers

• Multotec: South African global supplier of mineral processing equipment and wear products, including screen media, cyclone liners, and mill/grinding components. Overlaps with SWB in mining and aggregate processing wear parts with comparable engineering-led sales model.
• Magotteaux: Belgian-headquartered global leader in wear-resistant castings and grinding media for mining, cement, and recycling industries. Most directly comparable to SWB across product portfolio (crusher parts, grinding balls, hammer-type wear parts) and customer base in metal recycling and aggregates.
• Bradken: Australian-headquartered (now part of Hitachi) global supplier of wear-resistant engineered products for mining, resources, and rail. Manufactures grinding media, crusher liners, and mill liners using similar casting and alloy-steel methodologies as SWB.
• Castolin Eutectic: Specialist in wear protection solutions including hardfacing alloys, wear plates, and brazing products for industrial wear applications. Comparable to SWB on technical positioning around wear-life extension, though focused on overlay/repair solutions versus SWB's replacement casting approach.
• Durex Products: US-based manufacturer of polyurethane and rubber screening media plus specialty wear parts for aggregate, mining, and recycling. Adjacent competitor with significant overlap in wear-parts supply to similar OEM and end-user customers as SWB.
• Columbia Steel Casting Co. US-based manufacturer of replacement wear parts for mining, recycling, and aggregate processing — including shredder hammers, grates, anvils, and crusher liners. Closest North American competitor to SWB in differentiated, application-engineered cast wear components.
