The best way to successfully weld SS to MS or even Hardened Tool steel to MS is to use Magna 303 welding rod mfg by Magna Industrial, Australia. It has been tried and tested and is the only successful way to weld different steels and the weld has a tensile strength of 1,20000 psi, but these rods are expensive and suitable primarily for maintanence or repair welding
during the welding of any pipes, pressure parts,ms to ss welds-energy/load/frequency/current needs to be constant rather than fluctating which will affect the weld deposition with in the gap which will lead to weld porosity. Rectrifire eliminates the above
To find two numbers that multiply to -317, we need to consider the factors of -317. The factors of 317 are 1, 11, 29, and 317. Since -317 is negative, the two numbers must have different signs. Therefore, the pair of numbers that multiply to -317 is -1 and 317.
-317
317 is a whole number. It is in its simplest form. You could have 317/1 but it should be simplified to 317.

317 + 1.5% = 317*1.015 = 321.755
SS 304L is a grade of Stainless Steel which has low carbon content as compares to normal grade of SS 304. Usually, Carbon content is less than 0.030%. It is used mainly in those applications where Stainless Steel components are to be welded and weld has to be very strong, leak proof.
2x-317 = -315
Depends on what you are welding, but generaly welds can meet, or even weld on top of a weld.
