Steel Castings – Properties, Casting Expertise & Applications
Introduction to Steel Castings
Steel castings deliver the combination of high strength, toughness, and pressure integrity that critical equipment demands. Compared with iron-based castings, steel grades offer superior impact resistance, weldability, and heat/low-temperature performance—making them the preferred choice for valves and pumps, power plant components, mining and cement machinery, construction equipment, and transport structures.
At TX Metal, we treat steel not just as a material, but as a complete engineering solution. Our metallurgy, simulation-driven gating design, and in-house heat treatment allow us to supply reliable, fully machined castings that meet international standards and your schedule.
Why Engineers Choose Steel Castings from TX Metal
- High Strength & Toughness – With controlled chemistry and heat treatment (N, Q&T, solution & temper), our castings resist shock, fatigue, and heavy loads.
- Pressure & Temperature Capability – Grades for cryogenic to high-temperature service keep valves, pumps, and turbine housings leak-tight and stable.
- Weldability & Repairability – Qualified WPS/PQR procedures support welding, hardfacing, and on-site repair.
- Design Flexibility – Complex shapes in a single piece reduce weldments and stress risers; near-net casting lowers machining time.
- Total Cost Efficiency – Robust process control minimizes defects and rework; integrated machining shortens lead time.
- Traceable Quality – Heat-by-heat chemistry, mechanical tests, and NDT records ensure full compliance.
