Could stainless steel self tapping countersunk screws be stiffened?

Mr. Pan from Shanghai said that he needs to order stainless steel self tapping countersunk screws, the strength of which is expected to reach grade 6.8. He asked if we could achieve his required strength through hardening.

Generally speaking, stainless steel screws can not be hardened, unless the material can be hardened into iron. But Mr. Pan said he didn’t want iron. He preferred stainless steel. Then Ms. Song suggested that Mr. Pan could change the material of sstainless steel self tapping countersunk screws to stainless steel 410, which can be hardened to achieve the strength required by Mr. Pan.

Mr. Pan said he would discuss with the project to see if the material can be changed to 410 stainless iron. And Mr. Pan also asked Ms. Song if she had a composition analysis table of 410 stainless iron that they needed to look at. Ms. Song then reported the composition of 410 stainless iron to Mr. Pan.

The next day, Mr. Pan went to Miss Song and asked if they could make samples first. They needed 50 samples of 410 stainless iron and 304 stainless steel for testing. After testing, they would determine which material they needed to use. And the Shi Shi Tong screw manufacturer is to accept proofing, soon Miss Song will proofing costs and production cycle told Mr. Pan.

If you also need to order stainless steel self tapping countersunk screws or other screws, please contact Shi Shi Tong screw supplier.
