FAQ
The core difference lies in molybdenum (Mo) content—316L contains 2-3% Mo, while 304 has none. As a 25+ year stainless steel export expert, ESANG recommends: 316L for superior corrosion resistance (seawater/chemicals, 1000h salt-spray test passed) , ideal for marine/pharmaceutical projects; 304 for cost-effective general use (construction/kitchenware). We provide free material samples to help you test suitability before bulk purchase.
