Application Fields420 stainless steel balls are commonly used in industries that demand high precision and corrosion resistance: motorcycle accessories, pulleys, stainless steel bearings, plastic bearings, handicrafts, valves, and oil.
FeaturesThe representative of Malleable Iron Steel, commonly known as stainless iron, is magnetic, with good corrosion resistance, and has a high hardness of HRC 50-55.
Magnetic
All Austenitic stainless steel balls are typically non-magnetic; after cold working, some magnetism may be noticeable. Standard: ISO3506 GB/T
3098.6 The characteristic of various materials' magnetizability also applies to stainless steel. It is only possible to be completely non-magnetic under a vacuum condition. The measurement of the magnetic permeability of a material in a magnetic field is relative to the material's magnetic permeability μr in a vacuum. If μr is close to 1, the material has a low magnetic permeability.
In daily life, we often encounterIs using a magnet to determine if it's stainless steel actually very wrong?。
Stainless steel is categorized intoAustenitic stainless steel and Martensitic stainless steelThe 201, 304, 316, and 316L series are Austenitic stainless steels without magnetic properties; while the 420, 430, 440, and 440C series are Martensitic stainless steels, commonly referred to as "rustless iron" in our country. The reason for this name is due to their magnetic properties. However, having magnetic properties doesn't necessarily mean poor corrosion resistance, let alone that magnetic materials are always iron. The 440 and 440C are top-notch stainless steels, known as special steels. They offer excellent corrosion resistance and high hardness, earning them the title of "stainless steel bearing steel." They are widely used in high-precision manufacturing industries.
Therefore, we cannot simply determine if an item is made of stainless steel based on whether it is attracted to a magnet or not. So 440 stainless steel ballOf course, it's made of stainless steel, and it's high-quality stainless steel, too.
We address all your concerns and answer your questions here, one by one.
How to choose steel balls?
(1). If you need high hardness and wear resistance, go for the bearing steel balls with wear resistance; secondly, choose the carbon steel balls that have been fired.
(2). If you need to weld something with low hardness, you should use carbon steel balls without heat treatment, commonly known as iron balls.
(3). For superior rust resistance, opt for stainless steel balls, available in grades 304, 316, and 316L, with increasing rust protection.
(4) For excellent rust prevention and high hardness, choose the 440 stainless steel ball.
(5). For high precision, choose a higher grade; the smaller the number, the higher the grade, and the better the precision.
If the above does not resolve your疑问, and you're still unsure about the type of steel ball you need, feel free to contact our customer service. Clearly explain your application, and our professional staff will provide you with a specialized solution to ensure your satisfaction!
2. Quality Assurance
(1). Raw Material Assurance: Steel billets sourced from major steel mills.
(2). Production Equipment Assurance: Introduction of production equipment and testing instruments.
(3). Technical Support: Over a decade of technicians are on 24/7 rotating duty to oversee and ensure production control.
(4). Strict and scientific production management system constraints: Rigorous management, adherence to production regulations, traceable responsibility reversal.
(5). A sealed, clean, and dust-free workshop: Ensures high precision production of precision steel balls.
3. Shipping Information
（1). Samples shipped via SF Express: A limited number of samples are available for free, with shipping charges to be paid by the recipient.
(2) Shipments under 300 kg use express services like Yousu Express, Best Express, Debang Logistics, Jiayi Logistics, Shangqiao Logistics, etc.
(3). For orders over 300 kg, we use dedicated logistics. Generally, customers pick up from the city's logistics center. If pickup at the county/district is required, please specify; additional delivery fees apply.
4. Packaging
We offer various packaging options, including woven bags, cardboard boxes, pallets, iron drums, bottled, and ton bags, and can customize packaging to meet customer requirements.
5. Regarding shipping origin
Due to our factory being located in a rural area, logistics and express delivery are not convenient. Therefore, we have rented a large warehouse in the large logistics park in Liao City to store goods and ship them to our customers.
6. Return and Exchange Policy
If it's our responsibility and the quality doesn't meet the standards, we cover the round-trip shipping costs for returns and exchanges. If it's the buyer's responsibility, returns and exchanges are possible as long as it doesn't affect resale, with the buyer covering the shipping costs both ways.
