JM Hardware® SS 409 Machine Screw
JM Hardware® Stainless Steel 409/ UNS No. S40900/ WNR 1.4512 Fastener
SS409 is a type of ferritic stainless steel that is primarily known for its excellent corrosion resistance and high-temperature performance. It is commonly used in environments where moderate corrosion resistance is required along with good mechanical properties. SS409 is an economical stainless steel option, which makes it particularly suitable for applications where cost efficiency is essential without sacrificing performance.

Product Introduction
Key Properties of SS409 Stainless Steel:
Corrosion Resistance:
SS409 offers good resistance to oxidation and corrosion, particularly in mildly corrosive environments such as automotive exhaust systems, where the material is exposed to exhaust gases and moisture. It performs well in environments with moderate heat and humidity, making it an excellent choice for outdoor and industrial use.
High-Temperature Tolerance:
One of the standout features of SS409 is its ability to withstand elevated temperatures without compromising its structural integrity. It retains its strength at temperatures as high as 600°C (1112°F), making it suitable for applications where exposure to heat is common, such as in exhaust systems and heating units.
Mechanical Strength:
Though not as strong as austenitic stainless steel, SS409 still maintains good mechanical properties, with moderate tensile strength and durability. Its formability and weldability make it easier to work with during the manufacturing process, especially for fasteners requiring customized shapes and designs.
Cost-Effective:
SS409 is an economical stainless steel alternative compared to other higher-grade stainless steels such as SS304 and SS316. This makes it a popular choice in industries where performance needs to be balanced with cost-efficiency.
Applications of SS409 Fasteners:
Automotive Industry: Widely used in automotive exhaust systems and mufflers due to its resistance to heat and corrosion.
Construction: Employed in outdoor structures, especially in moderate corrosive environments.
Industrial Equipment: Used in heat exchangers, boilers, and other equipment exposed to high temperatures and mild corrosive conditions.
Agriculture: Utilized in farm machinery and equipment that operate in humid or mildly corrosive environments.

Quality Control
JM Hardware conducts product quality control in strict accordance with ISO 9001 standards to ensure that our products meet high quality standards. Below are our five quality control steps:

1
Incoming material control
We carry out strict incoming material control by conducting dimensional tests on each batch of raw materials and checking the raw material reports from the steel mills. This ensures that the raw materials we use are within specification and provide a reliable basis for production.

First part control
After the mold assembly is completed, we conduct a thorough inspection of the first production part and make detailed records. Only qualified first parts can be released to start mass production. This step ensures that the quality of the product meets the standard at the beginning.

Self-inspection by workers during mass production
In the mass production process, we require the workers of each machine to carry out self-inspection every hour. If any substandard product is found, we will immediately pick or scrap the production within this hour until the problem is solved and meets the standard of conformity, and then we can continue the production. This self-inspection mechanism helps to find and solve problems in time during the production process.

QC inspection during mass production
In addition, every two hours, the quality inspection personnel will carry out random inspection on the products of each machine. Only qualified products can continue to flow into the next production stage. If non-conforming products are found, we will take the same selection or scrapping measures and ensure that the problem is properly handled. This helps provide additional quality assurance.

Finished product control
Finally, after each batch of finished product is made, we conduct random inspections in proportion to the order. Qualified products will be packaged and put into storage, while unqualified products will be returned for further analysis and rectification. We insist on ensuring that the quality of our products meets high standards so that we can provide reliable products to our customers.
