It has come to the attention of the ASTPM that Grade Q345, a standard in China, is being sold into the local market as equivalent to S355. An investigation into Q345, including a number of tests, has resulted in the following conclusions. The imported product is a Carbon Manganese steel while locally produced tube is typically produced with low Carbon micro-alloyed steel.
SAW flux-wire combinations, AC is recommended. Electric polarity can affect the usability of welding consumables and the chemical composition and mechanical properties of weld metals; therefore, it is recommended to confirm the performance of the consumable you selected, using the polarity of a power source available for a particular job. 3. Material Properties of S355 Steel - An OverviewAug 23, 2015 · S355 Yield Strength. S355 is named based on it's minimum yield strength of 355 Mpa (N/mm2), However the yield strength reduces when you go up in thickness above 16 mm for flat products & hollow sections. Here is the table showing reduction in yield strength based on thickness. Up to 16 mm - 355 Mpa. 16 mm < t 40 mm - 345 Mpa.
