Steel castings — castings from carbon (25L, 35L, 45L) and alloy (20GSL, 110G13L — wear-resistant manganese steel, 12Kh18N9TL — stainless) steels. According to customer drawings. Methods: sand casting (CTS), shell mold casting, investment casting (LVM, accuracy IT9–IT11, Ra 6.3–12.5). Weight from 0.1 kg (LVM) to 10 tons (sand casting). Heat treatment: normalization, quenching + tempering. Control: X-ray, ultrasonic testing (UT), magnetic particle inspection (defectoscopy). GOST 977-88. CNC machining — finishing dimensions. 110G13L (Hadfield steel) — manganese austenitic steel with work hardening effect upon impact. For crusher jaws, mill liners, railway crossing frogs. Hardness HB 180 (as-supplied) → HRC 50 (after work hardening). Documentation: melt certificate, mechanical test report, UT report. Products comply with GOST and international standards. Export documentation: quality certificate, test report. Wholesale supplies. Technical consultation.
