Black spots found on nickel plated surface

The base metal are copper material also OFC materials. It is difficult for us to find out the root cause of the problems, as sometime the H2O2 and dummy plating cannot solve the problem. The pre-treatment process is effective and I believe the black spots on the surface are not due to the dirt attached on the raw material which cannot be High Speed Steel Tool Steel P20 Mold Steel P20P20 Mold Steel. P20 Mold Steel is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels. The steel is commonly used for plastic injection mold cavities and tooling and for die casting dies for zinc. P20 is typically sold in the pre-hardened condition at a hardness of approximately 300 HBW. Composition

Mold steel - P20 or not P20? - Canadian Metalworking

Apr 25, 2013 · P20 is almost synonymous with injection mold steels, and with good reason. What is P20? The popular material is compositional ly very similar to the aerospace 41XX chromoly steel. Carbon content is typically a full 0.40 percent, so its not surprising that P20 is an oil-hardening steel, quenching after a thorough soak at 830C. P20 Steel Plate P20 Mold Steel 1.2311 3Cr2Mo - Otai We are P20 Steel Plate supplier for more than 2 decades.

Stainless Steel:how problems arise and how to avoid

Stainless Steel:how problems arise and how to avoid Them Table 1. common Types of Stainless Steel stainless steel is a chromium alloy steel thats resistant to rusting and corrosion. The particular application for which stainless steel will be used determines the type and grade of stainless steel. Steel Standards - ASTM InternationalASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.
