304 Stainless Steel BallA widely-used ball bearing suitable for applications in chemicals, aviation, aerospace, plastic hardware, perfume bottles, spray bottles, valves, nail polish, motors, switches, irons, washing machines, refrigerators, air conditioners, automotive parts, bearings, instruments, and baby bottles.
Features:
Typical representative of the Austenitic type, generally non-magnetic but magnetized after passing through a light ball, can be demagnetized. Offers excellent corrosion and rust resistance.
Comparison:
304HC stainless steel balls are softer and more easily machinable than 304 stainless steel balls, while 304L stainless steel balls offer superior rust and corrosion resistance compared to both, are easy to weld, and have excellent polishing properties, making them more suitable for industries with high surface quality requirements.。
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 magnetic properties of various materials, applicable to stainless steel as well, only become completely non-magnetic under vacuum conditions. Materials in a magnetic fieldThe measurement of the permeability is relative to the material's permeability in a vacuum.μr, if close to 1, indicates the material has low permeability.
In everyday life, we often encounterUsing a magnet to determine if it's stainless steel is actually a very incorrect method of judgment.。
Stainless steel is categorized intoAustenitic stainless steel and Martensitic stainless steel, wherein201, 304, 316, and 316L represent Austenitic stainless steels that are non-magnetic; while 420, 430, 440, and 440C represent Martensitic stainless steels, commonly known as "rustproof iron" in our country. The reason it's called "rustproof iron" is due to its magnetic properties. However, not all magnetic rustproof capabilities are poor, let alone if they are magnetic, they are iron. Among them, 440 and 440C are top performers in stainless steels, known as special steel. They have excellent rust and corrosion resistance, high hardness, and are referred to as stainless steel bearing steel, widely used in high-precision manufacturing industries.
Therefore, we cannot simply determine if a material is stainless steel based on whether a magnet sticks to it 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 one by one:
How to choose steel balls?
(1). If you're looking for high hardness and wear resistance, opt for bearing steel balls, followed by fire-hardened carbon steel balls.
(2). For welding, if you need a low-hardness ball, use carbon steel balls without heat treatment, commonly known as iron balls.
(3). For superior rust prevention, opt for stainless steel balls, available in grades 304, 316, and 316L, with rust resistance increasing in order.
(4). For excellent rust prevention and high hardness, opt for 440 stainless steel balls.
(5). For high precision, choose a higher grade; the smaller the number, the higher the grade, and the better the precision.
If the above doesn't resolve your疑问, and you're still unsure about the type of steel ball you need, feel free to ask our customer service. Clearly explain your application, and our professional staff will provide you with a satisfactory solution!
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 rotational duty to ensure production and quality control.
(4). Rigorous production management system with strict controls: stringent management, adherence to production regulations, and traceable accountability.
(5). Sealed and clean dust-free workshop: Ensures high precision production of precision steel balls.
3. Shipment Information
（1). Samples via SF Express: A limited number of samples are available free of charge, with shipping charges to be paid by the recipient.
(2) Shipments under 300 kg use Yousu Express, Best Express, Deppon Logistics, Jiayi Logistics, Shangqiao Logistics, etc.
(3). Shipments over 300 kg use dedicated logistics, usually picked up at city logistics, or specify for pickup at the county/district; additional delivery fee applies.
4. Packaging
We offer a variety of packaging options, including woven bags, cardboard boxes, pallets, iron drums, bottled, and ton bags, and can customize packaging to meet customer requirements.
5. Where is the shipment origin?
Our factory is located in the countryside, where logistics and express delivery are not convenient. Therefore, we rent a large warehouse in the Liaocheng City's major logistics park to store goods and ship them out to our customers.
6. Return and Exchange Policy
If the responsibility is on our side due to quality issues, we cover the round-trip shipping costs for returns and exchanges. If the responsibility lies with the buyer, returns and exchanges are possible as long as it doesn't affect resale, with the buyer covering the shipping costs both ways.
