Welding Stainless Steel

Understanding Stainless Steel

What is Stainless Steel?

Stainless steel is a metal alloy based on iron. It’s a mixture of iron and other elements. Chromium is an essential metal known for its anticorrosive properties. This is because the chromium in the steel forms a layer of chromium dioxide on its surface, which makes it resistant to staining and rust. This is why many industries, such as automotive, aerospace, and construction, gravitate to stainless steel.

Types of Stainless Steels and their Welding Compatibility

Stainless steel doesn’t come in a single size. There are many types, each with their properties and welding requirements. Take a look at the following:

  • Austenitic Stainless Steel: Composed of 15-30% chromium and 2-20% Nickel. Non-magnetic and highly formable. Excellent for welding. Common grades include 304 or 316.
  • Ferritic Stainless steel: Contains 10.5-27% chromium and is magnetic. You can weld this type more efficiently than austenitic types, but you should use specific techniques. The most popular grades are 409 and 430.
  • Martensitic Stainless steel: Composed of 11.5-17% chromium with up to 1.2% Carbon. You can magnetically harden this type through heat treatment. It could be better for welding. The most common grades are 410 and 422.
  • Duplex Stainless Steel: A combination of austenitic & ferritic stainless steels, providing a balance in properties. They contain between 19-28% chrome and 4.5-8% nickel. They are still weldable, but they require more care.

Stainless Steel’s Characteristics Differentiate It from Other Metals

When it comes to welding, stainless steel has unique properties.

  • Corrosion Resistant: High chromium content creates a passive oxide film that resists corrosion. This property can be detrimental if it is not handled correctly during welding.
  • More excellent Melting Point:Stainless steel has a higher melting temperature than carbon steel. This affects the welding process.
  • Sensitization: The material around the weld may become sensitized. To retain its corrosion resistance, you should cool it quickly; otherwise, you must correct the welding process.
  • Thermal Conduction: Carbon steel is more thermally conductive than stainless steel. This means it will distribute heat differently and affect how you manage the weld pool.
  • Coefficient Thermal Expansion: It expands and contracts differently under heat. If you don’t handle it correctly, it can distort.

What to consider when choosing the suitable stainless steel for your project

ASTM Standards for Stainless Steel

It’s essential to consider the American Society for Testing and Materials standards when choosing stainless steel. These standards guide stainless steel grades’ composition, mechanical characteristics, and performance requirements. You can, for example:

  • ASTM-A240:This standard applies to chromium or chromium-nickel stainless steel plates, sheets, and strips for pressure vessels and other general applications.
  • ASTM-A276:This specification covers bars that have been hot-finished, cold-finished, or reformed. This specification covers round, square, hexagonal, hot-rolled, or extruded shapes such as angles, tees, and channels.

Consider factors such as corrosion resistance, strength, and cost.

Corrosion resistance

A material’s corrosion resistance is a priority for many projects, particularly those exposed to harsh environments. Austenitic grades such as 304 and 316 have high corrosion resistance because of their high content of chromium or nickel. Ferritic grades tend to be less resistant, but they can still be an option depending on your specific application.

Strengthening Your Body

The type of stainless steel you select will directly impact the finished product’s durability. Martensitic grades have a high degree of hardness but are less corrosion-resistant. Duplex stainless steels are a good compromise between strength and corrosion resistance.

Cost

Cost is another factor that businesses must recognize. Austenitic grades tend to be more expensive because of their nickel content. Ferritic grades contain less nickel and are, therefore, often cheaper. Martensitic grades are strong but require heat treatment, which can increase the cost. Consider the lifecycle costs of the material, including maintenance, potential replacements, and the initial price.

  • Interpass temperature: Be aware of the temperature in between passes. Heat can distort the metal and compromise its corrosion resistance.

How to achieve a clean weld

A strong weld starts with a clean weld. How to do it:

  • Gas coverage: Ensure your shielding gas covers the area you will weld. Gas contamination can occur if there is not enough gas.
  • Watch the Weld Pool:You risk losing control and increasing the spatter if it grows too big.
  • Tungsten Angle (for TIG): Keep your tungsten angle between 10-30 degrees to maintain reasonable arc control.
  • Short Circuit Parameters for MIG: To minimize spatter, adjust the short circuit parameters of your MIG machine to improve bead appearance.

After-weld Cleaning and Polishing

It’s complete once the weld is clean.

  • Visual inspection: Begin a visual inspection to check for irregularities or inconsistencies.
  • Grinding: If necessary, use a grinder wheel to smooth the weld.
  • Cleaning Solution:There are specific stainless-steel cleaning solutions that can remove oxidation from the metal and restore its natural luster.
  • Polishing: A final polish improves corrosion resistance and enhances the appearance of metals by removing micro-imperfections where contaminants can collect.

Do you make these common mistakes when welding stainless steel?

Preparation is not adequate

Why would you weld onto a surface that is not prepared?

  • Surface Contamination: Always clean stainless steel thoroughly. Any contamination, whether oil, dirt, or anything else, can negatively affect your weld.
  • Material Alignment: Ensure the pieces are aligned correctly and clamped securely.
  • Practice runs: Before you start, test your settings on scrap material. This step will save you from a lot more frustration in the future.
