30CrNiMo material investment castings

Our 30CrNiMo material investment castings are produced via mature silica sol lost wax investment casting technology, one of the most popular high-strength alloy steel cast solutions for heavy-load industrial fields. Made from premium 30CrNiMo nickel-chromium-molybdenum alloy steel, these precision cast components combine outstanding tensile strength, superior impact toughness and reliable abrasion resistance after standardized heat treatment including quenching and tempering.

We support full OEM & ODM customized production according to clients’ drawings, samples or technical specifications, covering dimension adjustment, surface finishing (machining, polishing, shot blasting) and hardness customization. Strict raw material incoming inspection and full-process dimensional testing are carried out during production to meet railway equipment, mining machinery, hydraulic pump, engineering vehicle and heavy-duty transmission part application standards.

Compared with conventional sand casting, investment casting realizes tighter dimensional tolerance and smoother casting surface, greatly reducing subsequent CNC machining workload. Our 30CrNiMo castings have been widely exported to Europe, North America and Southeast Asia for railroad spare parts, construction machinery fittings and high-load mechanical accessories, with complete material test certificates available upon customer request.
