Hello, this is HDC.

​

Stainless steel is one of the most versatile and essential metal materials in modern industry.

It has the advantage of being able to be used in a variety of industrial fields while maintaining an excellent balance of strength, ductility, and durability.

However, not all steels have the same properties, and their performance and uses vary greatly depending on their chemical composition and microstructure.

Today we're going to take a closer look at this!

｜Types of steel

Steel is classified into several types depending on the alloying elements it contains.

Among them, carbon is the main alloying element, and other elements are included in small amounts. “Carbon Steel”It is called.

Carbon steel is one of the most widely used types,

Its simple composition and excellent versatility make it a key player in a wide range of industries, from structures to precision tools.

​

On the other hand, steels are made with added elements such as chromium, nickel, and molybdenum to enhance specific performance. “Alloy Steel”It is said,

Stainless steel, which we will learn about today, is also one type of alloy steel.

✅ 1) Carbon Steel

– Steel in which carbon is the main alloying element

• low carbon steel : It is soft and has excellent processability, so it is used for structural members (beams, pipes, etc.)

• medium carbon steel : Increased strength and hardness make it suitable for machine parts such as gears, shafts, and springs.

• high carbon steel : It has high hardness and is used for cutting tools, steel wire, etc.

​

✅ 2) Alloy Steel

– Steel with added elements such as chromium, nickel, and molybdenum to enhance specific performance

• low alloy steel : Small amounts of alloying elements are added to improve performance.

• high alloy steel : Used in environments requiring high corrosion resistance and high temperature properties; stainless steel also falls into this category.

｜Meltio's Stainless Steel

Stainless steel has excellent performance due to its special chemical composition.

It has strong corrosion resistance, can adapt to various environments, and is easy to maintain.

Meltio's 316L material is a modified alloy stainless steel containing more silicon (Si) than standard 316L and, when used with advanced additive manufacturing technologies, delivers outstanding performance, including:

__________________________________________________________________________________________________________

✔ Improved corrosion resistance

– Excellent corrosion resistance even in highly corrosive environments such as acidic substances or seawater

​

✔ Excellent weldability

– The silicon (Si) content ensures clean welds and stable welding quality.

​

✔ Reduced risk of intergranular corrosion

– High resistance to intergranular corrosion due to suppression of precipitation of intergranular carbides after welding due to low carbon composition

｜Stainless Steel 316L in Meltio System

Additive manufacturing processes using lasers and wires are known to be manufacturing methods in which temperature changes occur very quickly during the process.

After the laser passes through, the molten state is rapidly cooled, which determines the microstructure that is ultimately formed.

Meltio's Stainless Steel 316L also exhibits these characteristics without exception.

Due to rapid temperature changes during manufacturing, the microstructure may sometimes be directional.

However, this is an improved result compared to other DED processes, and structural homogeneity can be further improved through heat treatment if necessary.

​

When performing mechanical testing,

There may be slight differences in tensile strength between directions parallel and perpendicular to the stacking direction of the component.
