						Description and Applications | 
					
					
						
						HM310 is a gas 
						metal arc welding wire to be used with Ar+0.5∼2%O2 
						shield gas. Deposited metal contains a full austenitic 
						structure with excellent corrosion, acid, and heat 
						resistibility. 
						 
						Welding of 25% Cr-20% Ni stainless steel, dissimilar 
						metals such as 18% Cr-8%Ni stainless steel to carbon 
						steels for petroleum and chemical industries. |

						Guideline in Usage 
						 | 
					
					
						
						
							
								
						
							
								| 
								When high 
								X-ray quality is required, stable spray transfer 
								mode should be maintained with low current and 
								slow welding speed using a pulsed arc and power 
								source. |
