Welding Wire Cast and Helix: How to Measure and Specify Them

Quick Answer Cast is the natural loop diameter formed by welding wire after it is released from its package. Helix is the out-of-plane rise of that loop above a flat reference surface. Together, they can influence how consistently wire travels through the feeding system and where it exits the c... Read More

Hollow Bar vs Seamless Tube: Which Is Better for Machined Components?

Quick Answer: Choose stainless steel hollow bar when the part will be heavily machined into sleeves, bushings, rings, cylinders or other bored components and reducing drilling and rough-boring work is important. Choose seamless tube when the order is governed by a tube standard, pressure or flu... Read More

316Ti vs 316L Stainless Steel: Stabilization, Welding and Selection

Quick answer: 316L and 316Ti are molybdenum-alloyed austenitic stainless steels with similar general corrosion resistance, but they control sensitization in different ways. 316L uses a low carbon limit to improve weldability and reduce carbide precipitation, while 316Ti contains titanium to stab...

Why Does Stainless Steel Spring Strip Curl or Wander? Coil Set, Camber and Flatness Explained

Spring Strip That Curls or Tracks Sideways: What the Shape Is Telling You Quick answer: Stainless steel spring strip may curl, wander sideways or refuse to lie flat because of coil set, edge camber, crossbow, local waviness or uneven residual stress. These conditions are not interchangeable. A ... Read More

Hydrostatic Test vs Eddy Current Test for Stainless Steel Tube

Quick Answer: A hydrostatic test checks whether a stainless steel tube can withstand the specified internal test pressure without visible leakage.
