Why SpaceX Chose 304L Stainless Steel for Starship?

From Carbon Fiber to Steel In the early stages of the Starship program (formerly BFR), SpaceX initially intended to use advanced carbon fiber composites. However, in late 2018, Elon Musk announced a radical pivot to 304L stainless steel. To understand why, we must look at the specific therma... Read More

Stainless Steel Laser Cutting and Ordinary Cutting

Stainless Steel Cutting Stainless steel is widely used across industries from construction to kitchenware, but its high strength and hardness make cutting a critical challenge. In the processing field, laser cutting and traditional ordinary cutting (such as plasma cutting, shearing, punching... Read More

Why Stainless Steel Warps During Processing

Why Stainless Steel is Different Stainless steel warps during processing primarily due to its high coefficient of thermal expansion and low thermal conductivity, which create significant internal stresses when the material is subjected to heat or mechanical force. Warping, or “distorti... Read More
