If you’re in the Houston area, suppliers like SteelNow and MetalMaster Inc. have got you covered with stainless steel 440C angle sections. These come in leg sizes ranging from 10 × 10 mm to 50 × 50 mm and can be as thick as 12 mm. You can choose from various finishes, including annealed, polished, and heat-treated, and they’re cut to your desired length, complete with certificates that meet ASTM and AMS standards. These local manufacturers are known for their quick delivery throughout Greater Houston, serving industries like aerospace, industrial tooling, chemical processing, and marine. Plus, they offer value-added services such as precision cutting, heat treatment, and surface finishing to ensure that every component meets strict requirements for hardness, clarity, and dimensional accuracy.
Now, let’s talk about stainless steel 440C itself. This high-carbon martensitic alloy contains about 16–18 % chromium and 0.95–1.20 % carbon, along with small amounts of manganese, silicon, and molybdenum. When it’s in its annealed state, it boasts a tensile strength of around 760 MPa, a yield strength between 425–450 MPa, and an elongation of about 14 %. With the right hardening and tempering, its tensile strength can soar past 1,900 MPa, and it can achieve a hardness of 57–60 HRC, although elongation will drop to 2–4 %. The alloy also has a Young’s modulus close to 200 GPa, magnetic properties, and a density of about 7.74 g/cm³.

Stainless steel 440C angle offers several advantages including high hardness and excellent wear resistance, making it ideal for heavy load and abrasion applications especially in sensitive corrosive And corrosion environments high resistance, due to its high chromium content. The ability to retain energy at high temperatures makes it suitable for high temperature applications. The material is also very durable, making it last longer and less maintenance. Stainless steel 440C angle is commonly used in the manufacture of tool, machine parts and high performance valves. Its strength and durability make it highly reliable in harsh industrial environments.
440C stainless steel angles are perfect for applications where outstanding hardness, wear resistance, and edge retention are essential. In the aerospace and defense sectors, you’ll find them in valve seats, bearing races, bushings, and other precision components. They’re also used in industrial tooling for dies, cutting tools, and pump parts that face abrasion. Cutlery makers love 440C for knife blades that need to stay sharp even with heavy use. In chemical or food-processing settings, polished angles provide hygienic and durable supports and brackets. Their corrosion resistance makes them a great fit for marine and petrochemical applications, where polished, hardened components are exposed to moisture and chemicals.
