We are a leading manufacturer, supplier, and exporter of EN30B Round Bar Alloy Steel Round Hex Bars Rods Suppliers, and Traders, according to ASTM B 473 Standards. The EN30B standard is widely used for plastic molds but is also suitable for several other applications. In pressure die casting tooling, EN30B Round Bars are used primarily for rivet snaps, air-hardening cold chisels, crimping tools, clutch keys, racks, pinions, and angle pins. As a rule, the hardening process entails smothering in air or oil from 810-830°C and treating with stunning mechanical properties.
We promise a movement of bleeding edge development and quality-based crude materials used for the era of the same.

Through hardening, EN30B Round Bar is a through-hardening steel composed of 4.5% Nickel, Chromium, and Molybdenum, which can harden in very large sections to give strength exceeding 1550N/mm2. Air from the hardening temperature can achieve these strengths since it is highly hardenable. Typically, this steel is used in applications that require high tensile strength and where more drastic quenches would result in distortion or cracking, especially in intricately designed parts. In some circles, it is still common for EN30B steel to be referred to as 835M30 steel, as it was the same grade under the old BS970:1955 standard.
EN30B is used for industrial purposes due to its high tensile strength and wear resistance. In addition to the high hardness of EN30B material, it has high tensile strength and wear resistance. Tronix Alloys provides our clients EN30B round with bars, forged bars, bright bars, and other sizes of premium quality. We are one of the most trusted manufacturers and exporters of EN30B steel bars. In addition to EN 30B round bars in hot rolled and bright condition, we also offer EN 30B flat bars.
It is possible to apply heat treatments to EN30B, such as normalizing, tempering, quenching, etc. It makes chains, screws, gears, arms, rollers, and other machine parts. Some of the applications of EN 30B are in the field of shipbuilding, aircraft design, mechanical engineering, oil production, and iron and steel processing.
Despite its widespread use for plastic molds, EN30B is also suitable for various other applications. Because of the steel’s strength, it can be used for compression, transfer, and injection molding, and since it is relatively free from distortion, it can be used in complex molds better than case hardening steels. As a result of the hardening process, which involves quenching in air or oil for 810-830°C followed by tempering, achieves excellent mechanical properties.

Chemical Composition Of EN30B Round Bar
| Grade | Element | ||||||

| EN-30B | 0.26-0.34% | 0.40-0.60% | 0.10-0.35% | 0.050% max | 0.050% max | 1.10-1.40% | 3.90-4.30%- |
This material has a very low carbon content of 0.26 – 0.34 percent and a relatively low Mn content of 0.5 – 0.6 percent. Its chemical composition contains relatively little carbon. It has a high Chromium content of 1.1-1.4 %, which causes it to be heat treated to increase yield and tensile strength. To ensure flexibility in the core of the part and high heat treatment temperature capabilities, a high Nickel content of 3.90%-4.30% is present. The contents of P are reduced to 0.05%, and S is reduced to 0.05 % max as excess content of P and S can damage the quality of steel and cause the alloy steel to break at low-stress points.

Typical Uses Of EN30B Round Bar
Typically, EN30B is used to manufacture gears, shafts, high-duty bolts, high-duty spindles, and other parts demanding high strength, toughness, or wear resistance. This steel is shocked in the annealed condition to render machining possible. It must be heat treated as follows: harden in air (or oil for larger sections over 2½” diameters) from 810°C / 830°C. Temper, if desired, at a suitable temperature or exceeding 250°C.
Forging:
Slowly and uniformly heat to 1050°C. Cool slowly after forging.
Stress Reliving
Whenever the machining operations have been severe, it is recommended to stress-relieve EN30B alloy steel before finishing machining and hardening. Heat carefully to 630-650°C, then cool in the furnace or still air after heating it.
Annealing
630/650°C should be heated uniformly. In the furnace, soak well and cool slowly.
Hardening:
Oil can be used to quench, or air can be used to cool. Slowly heat to 650/700°C and soak thoroughly. Allow the component to be heated to the final hardening temperature of 830/850°C.
Tempering:
Heat each inch of total thickness uniformly and thoroughly at the selected tempering temperature.
