410 is a Martinsitic material that can be joined to carbon steel using a 309Mo. Although the 410 and the carbon steel are not moly bearing steels, the 309Mo can be used, although a straight 309 is a better recommendation. A preheat of approximately 200-250 Deg. F. will allow the 2 different metal to cool down at a more even rate. The 410 can be used in the "as welded" condition. If a PWHT is required, it should be in the range of 1200-1400 Deg. F.
