Steel
61 years engineering steel castings for the most demanding industries — a nearshoring partner serving the United States, Canada and Mexico with USMCA-compliant supply. Carbon, low-alloy, stainless, refractory and custom steel alloys, all produced and machined under one roof.
Typical parts include valve bodies, pump housings, impellers, gears, brackets, and wear-resistant components.
Casting Weight Range
Supplied as-cast or fully CNC-machined
Materials
Carbon Steels
Valve bodies, pump casings, gas meters, structural brackets and pressure-containing parts.
Low Alloy Steels
High-temperature valves and pumps, refinery and petrochemical components, mining and oil & gas shafts.
Martensitic Stainless Steels
Hydraulic turbines, high-pressure valves, pump impellers and wear-resistant components.
Austenitic Stainless Steels
Cast equivalents of 304, 304L, 316, 316L and 317 — chemical, food and pharma.
Duplex & Super-Duplex Stainless
Mixed austenitic-ferritic structure — oil & gas, marine and chloride service.
Refractory Steels
Heat-resistant grades for cement kilns, hydrogen reformers and furnace internals.
Custom Steel Alloys
Proprietary and customer-specified compositions for unique performance requirements. Each request is reviewed and validated by our engineering team before quoting.
Typical Industries
Manufacturing Process
The client provides the product design. Fimex engineers how to cast it with in-house CAD/CAM using SolidWorks, PowerSHAPE, and PowerMill for pattern development and mold design. Wood, resin, or metal patterns fabricated to spec. Casting simulation with SolidCast to optimize geometry, predict shrinkage, and minimize defects before production.
Complex cores manufactured using two systems: Hot Box and Cold Box. Ceramic and silica sand cores ensure accurate internal channels and cavities, even for highly intricate geometries.
Two cluster molding processes for steel: Lost Foam and No-Bake Sand. Equipped with IMF systems, mixers, and HAST for consistent sand preparation and production efficiency.
Induction furnaces for steel alloys. Chemical analysis per heat ensures precise alloy composition. Controlled pouring temperature and speed for optimal casting integrity and traceability.
Controlled cooling rates to achieve target microstructure and mechanical properties. Sand separation and reclamation systems minimize waste and ensure sand quality for reuse in subsequent production cycles.
Grinding, shot blasting, and polishing to remove gates, risers, and surface imperfections. Parts inspected before advancing to heat treatment or machining.
Full heat treatment capabilities: Normalizing, Annealing, Quenching, and Tempering. Controlled furnaces ensure precise microstructure and target mechanical properties for each steel alloy and customer specification.
Dedicated steel machining floor: CNC horizontal & vertical machining centers, lathes, and conventional equipment. Optimized for steel alloy families.
Full dimensional, metallurgical, and NDT inspection per customer specifications. Destructive testing (Charpy impact, tension/tensile, cross-section cuts). Non-destructive: ultrasonic, liquid penetrant, magnetic particle, radiographic, hardness, chemical analysis, dimensional, and visual inspection. 3D scanning for reverse engineering and dimensional verification. Every steel part is verified before shipment.
