Types Of Stainless Steel
Before we get to the welding rods, you must familiarize yourself with the varieties of stainless steel available on the market. Though some common features are standard in every stainless steel, they differ in usage and other attributes.
So here is a short introduction to different types of steel.
Austenitic stainless steel
First, we have the austenitic stainless steel, the most common one of the bunch. Also, austenitic steel has the highest chromium ratio, making it more corrosion-resistant and nonmagnetic.
In addition, this type of stainless steel is known for its weldability and is therefore used for domestic use—architectural and transport projects.
Ferritic Stainless Steel
Then we have the ferritic steel, with a little less chromium and nickel content than the previous austenitic steel. Unlike austenitic steel, ferritic stainless steel is magnetic, and you can harden it by cold working.
Ferritic stainless steel is mainly used for kitchenware and automotive parts.
Martensitic Stainless Steel
The least common type of stainless steel is martensitic. It has lots of similarities to ferritic steel in terms of composition.
However, the carbon content in martensitic is much higher. Therefore it can be hardened quickly. This type of steel is used for knives and surgical instruments.
Which process is suitable for Welding Stainless Steel
Now that you know about the stainless steel variants let’s look at the options you can use to weld stainless steel.
Here is a little discussion about the standard welding process and its compatibility with stainless steel.
Primarily, TIG welding is considered stainless steel’s most ideal welding process. This process is used with shield gas like argon or argon mixed with other gas. TIG welding might be slow and expensive, but it’ll produce the best quality weld possible.
MIG welding is another reliable and widely used welding process for stainless steel. If you prefer durability, you can try welding MIG with stainless steel.
It’s also time and cost-efficient, but remember, it can ruin the tidiness.
You can use the stick welding method too for stainless steel. However, there is some catch. First, you’ll need the correct electrode, ideally a 308, 309, 310 or 312 SMAW. Each of them differs in price and joint quality.
Stick welding for stainless steel is mainly used for repair and maintenance projects.
Can you weld stainless steel with regular rods?
Every material has a compatible welding rod. Keeping this in mind, you cannot weld stainless steel with regular welding rods used in MIG or TIG welding made of materials other than stainless steel.
What type of welding rod is used for stainless steel?
Typically, only the graded welding rods are the best suited for welding stainless steel. More specifically, various grades of stainless steel and different welding rods are available to weld stainless steel.
Welding rods for different grade
Earlier I mentioned various grades of stainless steel. Instead of explaining these grades, I am discussing a few grades and their welding rods.
304: Let’s talk about 304 steel first. 3034-grade stainless steel falls under the austenitic category. As mentioned earlier, it has a higher chromium and nickel content of 16-26% and 8-22%, respectively.
This grade of stainless steel is weldable with 308 welding rods.
316: This is another stainless steel grade primarily used in the food industry in related applications. Whether it’s cutlery or kitchenware, 316 stainless steel is the ideal choice, and they are welded by 316 welding rods.
430: Next, we have 430 stainless steel, an option from the ferritic stainless steel group. As a general characteristic of ferritic steel, it has lower chromium and carbon content than 304 or 316-grade steel.
Therefore, 430 electrodes are used for welding this grade of steel.
434: Another ferritic stainless steel with wide usage across different industries. This stainless steel has extra molybdenum that increases the corrosion resistance. Like the previous grades, there are 434 welding rods available to weld 434 stainless steel.
Stainless steel welding rod buying guide
Welding might be complicated, but you can make it easier by selecting a suitable welding rod for your project. Here are some factors you should consider while purchasing a stainless steel welding rod.
If you want your weld last long, you need to check out the tensile strength of the welding rod. The minimum threshold here is to match the tensile strength of the welding rod with the base material.
You can avoid cracking and welding without damaging the base material. Usually, the first two digits of the AWS classification refer to the tensile strength.
Next, check the current source to weld with that particular welding rod. A special welding rod can only weld either with AC or DC. Additionally, some welding rods can work with both types of currents.
You should go for AC-compatible welding rods if your goal is deep penetration. The fourth digit of AWS classification refers to the current compatibility.
Base metal thickness
Just considering the welding rod features isn’t enough. Sometimes, you’ll also need to consider the thickness of the base material. The thickness will decide what type of welding rod can do the job.
If the base material is thick, you need higher flexibility and low hydrogen content welding rod. On the other hand, if the base material is thin, get a welding rod with a small diameter and soft arc
That’s a wrap for today. I hope my article was helpful enough to give you an idea about different types of stainless steel and comparable welding rods.
Welding stainless steel will be much easier now that you have the direction to the suitable welding rods.
Can you use 7018 on stainless?
7018 welding rods are primarily used for medium carbon, high carbon and low alloy steel. Unfortunately, stainless steel is none, and using 7018 on stainless steel can result in poor welding results with no strength and corrosion resistance.
Can I weld stainless steel with a stick welder?
Yes, you can weld stainless steel with a stick welder. Though stick welding stainless steel is not an ideal process, using the right electrode can bring decent results to repair and maintenance welding jobs.
