Latham Steel, located in Hamilton, New Zealand, stands out as a top manufacturer and supplier of Tool and Die Steel A2 Bars. They offer high-quality steel products that are crafted for exceptional wear resistance, toughness, and dimensional stability. A2 steel, known for its versatility as an air-hardening tool steel, is a go-to choice for applications that demand precision, strength, and durability. Latham Steel takes pride in ensuring that every A2 bar adheres to rigorous quality and international standards, making them perfect for tool-making, die manufacturing, and high-performance industrial tasks where reliability and longevity are essential.
These Tool and Die Steel A2 Bars are made up of about 1% carbon, 1% chromium, 1.5% molybdenum, and 0.5% vanadium, along with trace amounts of manganese and silicon. This specific blend results in remarkable hardness, wear resistance, and toughness, all while keeping good dimensional stability during heat treatment. Typically, A2 bars showcase a tensile strength ranging from 850 to 1000 MPa and a hardness of 57 to 62 HRC after proper heat treatment, making them ideal for heavy-duty tooling needs.

The standard annealing temperature for A2 tool and die steel bars is typically between 800°C to 850°C (1472°F to 1562°F), followed by slow cooling to relieve internal stresses and soften the material.
A2 tool and die steel bars resist corrosion through their high chromium content, forming a protective oxide layer that enhances resistance to rust and wear, especially in cold-work applications.
You’ll find Tool and Die Steel A2 Bars commonly used in the production of dies, punches, molds, cutting tools, and jigs across various industries, including automotive, aerospace, and general engineering. Their outstanding wear resistance and toughness make them perfect for high-stress operations, and their ability to maintain precise dimensions guarantees accuracy in tooling applications. A2 bars deliver dependable performance, a long service life, and require minimal maintenance, making them a top choice for engineers and toolmakers who need consistent quality and durability in critical applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
