Stainless Steel Ball Specification: 

 

Material

Feature

General Applications

AISI 420 

Magnetic, Harden-able, fair corrosion resistance 

used for special bearings and valves where Balls requiring a combine -action of hardness and corrosion resistance 

AISI 440C

Magnetic, highest hardness, good corrosion resistance 

used in bearing nozzles and valves where lubrication is poor or absent 

AISI 304

austentitic, corrosion resistance, slightly magnetic, however annealing can makes it non - magnetic 

Used in valves and relevant application , food products, aerosols, home sprays, perfumes and medical equipment. 

AISI 316

non - magnetic, good corrosion resistance even when exposed to marine atmosphere and sulfuric acid. 

used in presence of sulphuric, phosphoric and acetic acids.
Mainly used in chemical, paper and textile industries.

AISI 316

Characteristics same as 316 but with excellent corrosion resistance, Lower carbon content than regular 316.

Q:What are the casting parts tested?
The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.
Q:How much is the amount of electrophoretic paint per square meter used in the casting?
It was a very simple question, and it was complicated by what you said.
Q:What method of casting does not rust? I think the sample is like oil
The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.
Q:How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
The material is usually steel material price plus the cost (per ton of 2.5-3 million, plus profit).In the Yangtze River Delta region, generally 304 casting price of about 5-5.5 million / ton.The price will be higher if the parts are complex, or a piece weighs less than 100 grams.
Q:Cause of choking of casting parts
The reason is not in the coated sand, see coating gas evolution, the best use of zircon powder coating (low gas evolution), there is a mold according to a vent needle, this depends on your way is flat or vertical pouring pouring pouring, if vertical pouring, venting pin on the die, and the big piece how could the plane, pouring water flat, a breath, a taboo ah!
Q:Explain the heat treatment effect of casting parts, forging parts and welding parts
Good welding of low carbon steel (alloy), probably because the weld workpiece rigidity, fast cooling, the weld internal crystallization of brittle microstructure (martensite), so after welding or welding process welding using self heat, reasonable arrangement of weld, welding seam and heat affected zone heat treatment. The welding heat treatment is often used to preheat before welding, after welding withasbestos cloth covering slow cooling annealing, reach the purpose, its main function is to reduce the internal stress, improve the weld microstructure of martensite formation, reduce brittle tendency, preventing welding cracks.
Q:What reason is the bronze statue choking fire?
The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
Q:In theory, which is more expensive, forging parts or casting parts?
The structure of the casting is relatively flexible in design, and the modeling is easy to realize.
Q:How can the casting be free of trachoma?
3, the gate is not facing sand core, flush sand core, will cause trachoma.
Q:Can the casting part be phosphating with the phosphating solution of the pickling board?
Phosphating. But it's not necessary. Because casting parts have strong corrosion resistance.
