Can S30409 be welded using A102 welding rods, ensuring that the carbon content in A102 is 0.4-0.8%?

Thread Content

The unit is manufacturing a heat exchanger made of S30409, with a design temperature of 500°C; welding should be carried out using E308H electrodes, but it is difficult to obtain them locally. Since the amount used is small, can E308 (A102) be used as a substitute? Is it sufficient to ensure that the carbon content of the welding rod remains between 0.4% and 0.8%? Anyone who has had a similar experience please help confirm!
