What is CD4MCuN Hardened?

CD4MCuN is a duplex stainless steel alloy that is known for its excellent corrosion resistance properties. It is not typically hardened through traditional heat treatment methods like quenching and tempering, as these methods are not suitable for duplex stainless steels. Duplex stainless steels like CD4MCuN have a two-phase microstructure consisting of austenitic and ferritic phases. This microstructure provides the alloy with excellent strength and corrosion resistance properties, but it also...

How to weld mild steel to stainless steel?

Welding mild steel to stainless steel can be a challenge for new welders who are unsure of their ability to create a high-quality joint between these two dissimilar metals. The properties and compositions of these metals are different, making the welding process more difficult than welding pure stainless steel. In this article, we will discuss the challenges of welding mild steel to stainless steel and provide some tips to ensure a successful weld.Note: Mild steel (iron containing a small...

Reasons You Want to Avoid Welding Stainless Steel to Carbon Steel

When it comes to metalworking, welding is a commonly used technique to join different pieces of metal together. However, welding stainless steel to carbon steel is a particularly difficult task that should be avoided whenever possible. There are several reasons why welding dissimilar metals, such as stainless steel and carbon steel, can lead to problems and potentially compromise the strength and longevity of the finished product.DifficultyCombining dissimilar metals adds extra challenges to the...

Differences between Stainless Steel vs Carbon Steel?

Carbon steel and stainless steel are two common materials used in various applications. Here are some of the main differences between them: Composition: Carbon steel is an alloy of iron and carbon, with a maximum carbon content of 2.1%. Stainless steel is an alloy of iron, carbon, and at least 10.5% chromium, with other elements such as nickel and molybdenum added for specific properties. Corrosion resistance: Carbon steel is susceptible to corrosion and rust, especially in...
