Question Spring Newbie 2019/3/22(Fri) 17:22

When manufacturing springs, do you separate raw materials, such as SUS304 for SUS304-WPA and SUS304L for SUS304-WPB?

Answer Tokai Spring 2019/3/22(Fri) 17:34

Spring Newbie, thank you for your post!
Both SUS304 -WPA and SUS304-WPB are made from SUS304. The proper use of WPA and WPB will be selected at the design stage according to the shapes of the springs, spring characteristics, and usages.
SUS304L is not specified as WPA or WPB.
