We would like to introduce a case where we proposed a material change from SUS304 to SUS443 to customers who are considering a review of SUS304 materials in existing products and new product development. As an urgent issue, the price of stainless steel materials has skyrocketed compared to two years ago, making it necessary to review materials to reduce product costs. SUS443 is generally inexpensive and is characterized by higher corrosion resistance compared to SUS304. It also has low thermal expansion and high thermal conductivity, contributing to cost reduction.

In the current situation where the prices of materials such as stainless steel, aluminum, and iron used in precision sheet metal are soaring, we would like to introduce a case where we proposed dual-layer steel plates as an alternative to SUS304 for cost reduction. While SUS304 is excellent, its material cost is high, making the utilization of alternative materials during new product development an important issue for cost reduction. Dual-layer steel plates are less expensive than SUS304 and can enhance strength while reducing weight. They are also adopted in automobiles and industrial machinery, contributing to our customers' cost reduction. Additionally, it is possible to incorporate specific functions that cannot be achieved with a single material, such as improved thermal conductivity. [Challenges] ■ The prices of materials used in precision sheet metal are soaring, with SUS304 increasing by about 7% ■ Cost reduction through the use of alternative materials during new product development *For more details, please download the PDF or feel free to contact us.

We propose a chrome plating-free process that eliminates the chromate plating treatment and introduces a case where the production lead time for parts was shortened by one week. In response to frequent requests for short lead times for semiconductor equipment parts, the conventional chromate plating process extended the lead time. While cost reduction was also a challenge, customers particularly highlighted the shortening of lead times as the most critical issue. By changing from conventional steel materials to black ZAM materials with high corrosion-resistant plating, we were able to shorten lead times and achieve cost reductions of up to 10-20%. Furthermore, the dense plating layer unique to ZAM materials exhibits far superior corrosion resistance compared to conventional hot-dip galvanized steel sheets. [Challenges] ■ The conventional chromate plating process extended lead times in response to frequent requests for short lead times for semiconductor equipment parts. ■ Cost reduction and, in particular, lead time shortening are necessary. *For more details, please download the PDF or feel free to contact us.
