ASM FASTENER: Excellence Starts from Raw Materials

2025-08-06 14:47:12

At ASM FASTENER, we understand that the strength and reliability of any fastener lie in its foundation — the raw materials. As a trusted Chinese manufacturer specializing in fully threaded studs and industrial fasteners for over 14 years, we take pride in our rigorous raw material selection and quality control processes, ensuring that every product we deliver meets international standards and performs flawlessly in the most demanding applications.

High-Quality Raw Materials – The Backbone of Durable Fasteners

We use only premium-grade steel and alloy materials, sourced from certified and long-term partner steel mills that meet global quality standards. All incoming raw materials are supported by Mill Test Certificates (MTCs) and offer full traceability for chemical composition and mechanical properties.

The types of raw materials we typically use include:

• Alloy steels for heat-treated high-strength applications

• Austenitic and ferritic stainless steels for corrosion resistance

• Low-temperature and high-temperature steel grades

• Custom-formulated materials based on client technical specifications

These raw materials are carefully chosen to ensure they meet the strict requirements for mechanical strength, corrosion resistance, and dimensional stability.

From Raw Materials to Finished Products

ASM FASTENER manufactures a wide range of finished products using these high-quality raw materials, including:

• Stud bolts and threaded rods according to:

• ASTM A193 Grade B7 / B7M

• ASTM A320 Grade L7 / L7M

• ASTM A193 Grade B8 / B8M (Class 1 & 2)

• ASTM A193 Grade B16

• ASTM A320 Grade L43

• Other customized materials and grades based on project needs

Each product is precisely manufactured according to ASTM, ASME, or customer-specific requirements. We carry out heat treatment, threading, surface finishing, and final inspections in-house, ensuring full control over quality at every production stage.

Strict Material Testing and Quality Assurance

Before production begins, all raw materials undergo a comprehensive inspection process, including:

• Chemical analysis via spectrometers

• Mechanical testing for tensile strength, yield strength, elongation, and hardness

• Ultrasonic or surface inspection to detect flaws

• Dimensional and tolerance checks to confirm consistency

By maintaining strict quality control from the source material to the finished fastener, ASM FASTENER ensures outstanding performance in high-pressure, high-temperature, and corrosive environments — such as in shipbuilding, petrochemical plants, power stations, and offshore structures.

Reliable Supply, Global Confidence

Our well-managed raw material inventory and long-term relationships with steel suppliers allow us to guarantee fast delivery times and flexible order customization, even in times of global supply chain fluctuations. Many of our international customers rely on ASM FASTENER for consistent quality and on-time delivery.

At ASM FASTENER, raw materials are not just a starting point — they are a strategic asset. By sourcing only from certified suppliers and implementing strict quality checks, we provide our customers with products they can trust — every time, for every application.

Let us be your long-term partner in strength and reliability.
