The computer controlled induction quench and temper process has turned bar heat treatment
from an art to a science.
Individual bars proceed through the precision controlled heating coils while being rotated. Each bar enters the powerful quench where its temperature is rapidly decreased to transform the microstructure to the desired martensite structure. Next, it is tempered through more in-line coils to produce a tough custom-made product, superior in every aspect to the batch furnace product.
The Superquench process results in straight bars with no stress inducing mechanical straightening required. The process also results in bars that have a very good surface finish with no scale.
At Milltech, we believe in providing our customers with the best value at the lowest possible price.
Our products such as Superquench have superior properties that result in easier machining and less waste that result in savings compared to using lower cost material that may be more difficult to work with. Our experience has shown us that using lower cost feed material can actually increase costs and processing time providing no real overall saving.
We are also local suppliers who are happy to work closely with customers. We are able to provide technical support and advice and welcome visitors to our factories to observe our processes. Being local suppliers we are able to respond rapidly to urgent orders and customers have the ability to make changes right up to production time.
Yes we do.
Our ISO9001:2015 quality management system is accredited to ensure that customers are consistently provided with the highest standard of products every time.

We are manufacturers who support the Australian steel distributor network. We supply our products on a wholesale basis and have minimum order quantities for most products.
Orders less than the MOQ are possible but they do result in higher handling and shipping costs and may not be economical for customers. We are always happy to discuss special requirements.
The lead time on orders depends on the availability of stock. Our feedstock is generally sourced from Australian and high quality international suppliers. While we maintain a wide range of feedstock and finished products, there are occasions where we need to source feedstock from steel mills with lead times from two to four months.
"We now consistently get defect-free products that require little machining. the scale is thin and uniform so we don't have to machine the whole bar length. The Mechanical priorities are uniform throughout the bar and in every bar, which is a real bonus to both us and our customers in terms of field-performance."
"We find the Superquench product to be extremely stable when machining. Due to the improved quality of the bar, tool life is much improved. And the team much prefer using it, because they don't have as much hassle getting the job done."
