How to remove rust from stainless steel: A guide
article In the 1960s, steelmakers were developing new forms of steels with less than a tenth the strength of steel used today.
In some ways, they were the first to realise that if you wanted to improve performance, it was best to use less steel than was previously used.
In addition, the technology to make steel from this material was relatively easy to work with, and the steel industry was booming.
“The first industrial use of stainless steel was for making paper,” says John Lacey, professor of materials science and engineering at the University of New South Wales.
“That’s when it became the material of choice for a lot of people.”
That popularity has meant that, over the past 40 years, the use of new stainless steels has doubled.
But as steelmakers are now using this new material for a variety of applications, like building blocks, car components and other products, there is a growing concern that some parts of the steelmaking industry may not be getting the best use out of the new alloy.
“We’re seeing some new steel products being produced with an increased risk of corrosion,” says David Beddington, professor in the department of materials sciences and engineering, at the Queensland University of Technology.
“There’s some concern that there may be higher levels of corrosion, and therefore a higher risk of manufacturing failure.”
So, is it safe to use stainless steel?
The new material isn’t particularly tough to work on.
It’s only slightly more flexible than ordinary steel, but it’s stronger and more resistant to corrosion than steel from conventional sources.
That makes it ideal for the kinds of jobs that require it.
It also makes it a suitable choice for products that can be made with a wide range of stainless steaks, such as car body panels, car doors and other items.
“As an alloy, it’s good for high-strength applications, because the strength is increased in an area where steel is weak,” says Steve Rafferty, professor and director of materials engineering at James Cook University in Australia.
But it can also be a problem for low-strength steel products, like food packaging and medical implants.
Beddingham says the risk of stainless rust is high when using the new material.
“Stainless steel is a fairly brittle material,” he says.
“If you’re welding it to a piece of stainless, it can break easily.”
“It’s not easy to remove stainless steel rust.”
A key advantage of stainless is that it is much stronger than regular steel.
That means it is harder to crack.
“It is an alloy of three metals, which makes it extremely strong, and it can be welded to many types of metal,” says Beddingson.
“And it’s also relatively easy and cheap to produce.”
For high-value applications, stainless steel is also suitable for a wide variety of tasks.
For example, it is extremely flexible, which means it can easily be used to make a variety, and often very small, parts.
Biddington says it’s not surprising that stainless steel can be used for things like medical implants, but the process is more difficult with ordinary steel.
The process of making the implants is fairly simple: the metal is coated with the new metal, and then it is heated to between 200 and 200,000 degrees Celsius, which produces a hard, flexible layer.
Braid welders are also using stainless steppers for this purpose.
“You can weld these to the outside of a piece and you can put it in place, or you can use it to heat it up and then weld it back,” says Lacey.
“So you can make a lot more small parts with this material.”
If you’re using a car body, you can even use stainless stepper screws to make it easier to replace a broken part.
In this case, it doesn’t really matter whether the new steel has been hardened by welding it, as long as the parts are still steel.
“When you weld stainless steel to metal, it takes a long time, it will be very hard to get out of,” says Raffery.
“They can be very brittle, and there’s no good way to get them out of them.”
The new metal also means that it can perform better than steel in certain applications, such the car body.
Bids for the new aluminium alloy will start running on 18 April, but Bedding says the material will only become available to customers on a first come, first served basis.
“A number of manufacturers have already submitted applications for a limited supply of this new alloy,” he tells The Conversation.
“This is not something we have seen before in the aluminium industry.”
But it is the same company that won the tender to make aluminium parts for the Australian Bureau of Statistics.
“Aluminium is not an easy material to produce,” says the company’s head of manufacturing and technology, John Tully.
“With this new stainless steel, we’re able to do more with less.”
