Quality control

Quality control is fundamental to everything we do at Aobo Steel. Our testing team brings over 20 years of experience to the job. Their responsibility is to ensure every piece of tool steel meets strict standards before it ships.

Our quality process is thorough. It includes:

Chemical composition analysis
Metallographic examination
Hardness testing
Physical performance evaluation
Importantly, ultrasonic testing (UT) to check for any internal defects.

Crucially, we conduct a 100% quality inspection on every single product before shipment. This confirms it meets all required specifications and relevant industry standards.

For added assurance, we fully support third-party inspections if a customer requests it. This offers another layer of verification for the material quality.

This thorough approach means you can rely on Aobo Steel to deliver tool steel that performs dependably in your specific applications.

Who is suitable for working with us

Serving Small and Medium-Sized Factories

We understand that sourcing tool steel can be a challenge for small and medium-sized factories, particularly with high minimum order quantities (MOQs) from many suppliers. Aobo Steel addresses this directly: our MOQ is 5 tons. This allows you to acquire the necessary tool steel grades without committing to excessive volume or tying up capital in surplus stock.

Working with Aobo Steel means:

Manageable MOQ: Order quantities starting at just 5 tons.
Consistent Quality: All tool steel meets strict specifications for reliable performance in your production.
Ready Stock: Popular grades are often available from our inventory for faster delivery.

Partnering with Tool Steel Distributors

We understand that for tool steel distributors, competitiveness relies on pricing and reliable supply. Aobo Steel supports your business by offering competitive pricing structures and maintaining ready stock of key tool steel grades. This ensures you can respond quickly and effectively to your customers’ demands.

Partnering with us provides:

Competitive Pricing: Our rates are structured to support your margins.
Stock Availability: Key grades like D2, D3, H11, and H13 are consistently stocked for prompt shipment.

How we produce tool steel

The diagram below illustrates the production process of forged tool steel. Our production mainly focuses on providing high-quality forged round bars and plates. The process begins with melting and refining the raw materials, casting, and optional remelting for improved purity. The forged steel is then shaped, annealed for better machinability, and processed to remove the oxide scale. Finally, surface finishing is applied to ensure the desired quality and appearance.

This image shows an Electroslag Remelting (ESR) machine in operation. ESR is a specialized process used to improve the purity and quality of steel. During this process, a pre-cast ingot is remelted under a layer of molten slag, which acts as a purifier by removing impurities and inclusions. The refined steel solidifies as it cools, resulting in a material with a uniform structure, enhanced mechanical properties, and superior surface quality. This process is essential for producing high-performance tool steels and other critical materials.

In this video, you can see the forging process of a heated tool steel ingot. After being heated to the required temperature, the tool steel ingot is placed under a mechanical press. The forging press applies immense pressure to shape the steel into the desired form, enhancing its internal structure and mechanical properties. This process eliminates internal defects, refines the grain structure, and improves the material’s strength and durability, making it ideal for high-performance applications.

This video showcases a centerless grinding machine processing a tool steel round bar. In this operation, the round bar is precisely ground to achieve the required diameter and surface finish without needing a center to hold the material. This high-efficiency process ensures excellent dimensional accuracy, smooth surface quality, and consistent roundness, making the finished product suitable for demanding industrial applications.
