With precision manufacturing and strict compliance with international quality standards, Neil Metals provides wear-resistant and corrosion-resistant stainless steel bars for high-stress applications. With sophisticated production units and customer-oriented strategies, the organization caters to numerous industries such as power generation, automotive, mechanical engineering, and oil & gas. Square bars of Stainless Steel 1.4122 from Neil Metals are strong, hard, and durable and thus are best suited for the critical parts and long-term industrial applications.
**Stainless Steel 1.4122 Square Bars**, or X39CrMo17-1, are martensitic stainless steel bars with a **16–18% Chromium**, **0.9–1.2% Molybdenum**, and **0.35–0.45% Carbon** composition, with trace amounts of elements such as Manganese, Silicon, and Sulfur. Stainless steel grade offers high hardness and superior wear resistance following heat treatment. Mechanical properties consist of a **tensile strength of 850–1000 MPa**, **yield strength over 650 MPa**, and **good impact strength**. The alloy combines corrosion resistance with excellent mechanical strength and hence is used in applications where there is dynamic loading and moderate corrosion environment.

**Stainless Steel 1.4122 Square Bars** find extensive applications in applications where a balance of strength, wear resistance, and moderate corrosion resistance is necessary. Typical applications are **turbine blades, shafts, valve components, pumps, fasteners, and high-stress mechanical parts**. These bars are likewise employed in **automotive and power equipment**, particularly in components that are exposed to friction and temperature cycles. Their hardenability by heat treatment renders them appropriate for **precision tools and structural components** that are subjected to repeated loading. The material’s strength and dependability render it suitable for critical operations in **energy, machinery, and transportation industries**.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
