Factory Cheap 420c Stainless Steel Balls - 420C stainless steel balls high quality precision – Mingzhu Detail:

420C stainless steel balls are primarily used in Special bearings, anti-friction bearings, special pumps, recirculating balls, medical instruments, lighters, automotive seat-belts, oil refinery devices and components.

420C stainless steel balls. This type of stainless steels has good resistance against corrosion together with the high hardness. The balls made of this material are suitable for valves, special bearing etc., in which the protection against rustproof-grease is poor or absent. Their resistance against corrosion caused by water, steam, air, is good. This kind of steel is not suitable to be used with chemical agents like sea water and strong acids (even if diluted).

420C is similar to 420. It has a higher C chemical content, so the hardness is also higher than 420.

FAQ

Q: How do I choose the appropriate stainless steel brand (304(L)/316(L)/420(C)/440(C))? What are the main differences between 300 and 400 series stainless steel balls?
A:  To choose the proper steel brand for stainless steel balls, we should get to know well the properties of each brand and the application of the balls. The most common used stainless steel balls can be divided simply in two groups: 300 series and 400 series.
300 series “austenitic” stainless steel balls contain more chromium and nickel elements and are theoretically non-magnetic (actually are very low-magnetic. Totally non-magnetic require additionally heat treated.). Normally they are produced without the heat treatment process. They have better corrosion resistance than 400 series (in fact, the highest corrosion resistance of the stainless group. Although 300 series balls are all quite resistant, however 316 and 304 balls show different resistance to some substance. For more details, please refer to pages of different stainless steel balls) . They are less brittle, so can be applied also for sealing use. 400 series stainless steel balls contain more carbon, which makes it magnetic and more hardness. They can be easily heat treated like chrome steel balls or carbon steel balls to increase hardness. 400 series stainless steel balls are commonly used for applications that demand water-resistance, strength, hardness and wear resistance.

Q: What standards do you adhere to for manufacturing?
A: Our products are in compliance with the following standards industrial for steel balls:
● ISO 3290 (INTERNATIONAL)
● DIN 5401 (GER)
● AISI/ AFBMA (USA)
● JIS B1501 (JAP)
● GB/T308 (CHN)

Q: What kind of certificates do you achieve?
A: We own ISO9001:2008 management system certification and IATF16949: 2016 automotive industry quality management system certification.

Q: How is your quality assurance?
A: All produced balls are 100% sorted by the sorting bar and checked by the photoelectric surface defect detector. Before packaging samples balls from the lot are to send for final inspection to check for the roughness, roundness, hardness, variation, crush load and vibration in compliance with the standard. If all requirements are met, a inspection report will be made for the customer. Our sophisticated laboratory is equipped with high precision machines and equipment: Rockwell hardness tester, Vickers hardness tester, crushing load machine, roughness meter, roundness meter, diameter comparator, metallographic microscope, vibration measuring instrument, etc..

Q: Do you offer free samples for test?
A: Yes, we provide free samples to test and check quality.

Q: How long is your lead time?
A: Generally it takes around 3-5 days if the products are in stock. Or else the estimated lead time should be worked out according to your specific quantity, material and grade.

Q: We are not familiar with the international transportation. Will you handle all logistics?
A: Definitely, we deal with the logistic issues with our cooperated international freight forwarders with years’ of experience. The customers only need to provide us the basic information

Q: How is your packaging method?
A: 1. Conventional packaging method: 4 Inner boxes (14.5cm*9.5cm*8cm) per master carton (30cm*20cm*17cm) with dry plastic bag with VCI anti-rust paper or oiled plastic bag, 24 cartons per wooden pallet (80cm*60cm*65cm). Each carton weighs roughly 23kgs;
2.Steel drum packaging method: 4 steel drums (∅35cm*55cm) with dry plastic bag with VCI anti-rust paper or oiled plastic bag,4 drums per wooden pallet (74cm*74cm*55cm);
3.Customized packaging as per customer’s requirement.
