Frequently Asked Questions
- What the difference between of NBS55 and NBS60? Tell me about the difference of chemical composition
- It is different to make original materials by S55C or S60C. It is said about the chemical composition as well. And, there is difference of hardness.
- want to make an estimate of DP-2 mirror
-
Each time, we deal with the estimate. It causes distortion depends on size. Ex) RFQ 3.00 x 600 x 1500 one sheet and 5.0 x 600 x 1500 one sheet We do not have DP-2 more than 3mm. Please consider until 2mm. It is unmarketable goods for a full-length mirror because of big size.
About the size or detail of other DP-2 mirrors
Card mold, A4 size, 1500X2000(wall), washing face, sink, mirror for safety check
- Is it different a way of measuring between Vickers’ hardness and HRA scale? And don’t you have them more than HRA 90?
- Both is going to pressurize into diamond conical indenters and then it measures by size of the hollowness. The distinction between them is HRA is 60kg weight and Vickers is around 10kg weight (it depends on things). HRA 90 is almost same as Vickers’ 1000. It is written on a conversion table because there are not hard materials too much. However, it is possible for such as Hard Chromium Plating to be more than 1000 on the surface hardness.
