When purchasing stainless steel, customers often ask:“304 stainless steel is more expensive. Can we replace it with 430?”AISI 430 is a ferritic stainless steel primarily alloyed with chromium, while AISI 304 is an austenitic stainless steel containing chromium and nickel. The two grades differ signi

When purchasing stainless steel, corrosion resistance is one of the properties buyers frequently pay close attention to.Customers often ask:“How many hours of salt spray testing can this stainless steel pass?”Or:“Material A lasts longer than Material B in a salt spray test. Does that mean Material A

When customers choose austenitic stainless steel, three grades often come up: 1.4301, 1.4404, and 1.4541, commonly corresponding to 304, 316L, and 321.They may look very similar, and many of their processing characteristics overlap, but their performance can be quite different once they are put into

When purchasing stainless steel, “cold-rolled or hot-rolled?” sounds like a basic question. But once it comes to an actual project, the answer is rarely that simple.Some customers care most about the surface. They want it flat, clean, smooth, and free from obvious oxide scale. Others focus more on t

When purchasing stainless steel strip, especially precision stainless steel strip, customers usually pay close attention to material grade, thickness, width, hardness, surface finish, and surface roughness. However, there is another important parameter that is often overlooked — edge condition.Diffe

A few days ago, our sales team forwarded a customer drawing to us. It contained only one surface requirement: “Ra 0.2.”Our technical team asked the customer a few follow-up questions: What sampling length should be used? Should the measurement be taken in the rolling direction or transverse directio

When selecting stainless steel, 1.4034 and 1.4116 are two martensitic stainless steel grades that are frequently compared. Both belong to the European EN system and can be hardened by heat treatment. They are widely used in knives, medical instruments, and precision components. However, they differ

Brake discs are safety-critical components in the braking systems of motorcycles, electric vehicles, and bicycles. During operation, they are exposed to continuous friction, temperature fluctuations, and demanding environmental conditions. Consequently, the chemical composition, mechanical propertie

Both 1.4021 and 1.4028 are 13% chromium martensitic stainless steels. Their hardness and strength can be increased through quenching and tempering. Since both grades are commonly classified within the AISI 420 family, they are sometimes mistaken for the same material during material selection or quo
