BilletSteel WordPress Theme

Overview

Billet is a heavy steel forging and fabrication works theme — open-die forging, closed-die/drop forging, seamless rolled rings, heat treatment, and NDT-inspected custom fabrication for energy, oil & gas, aerospace, mining, and marine clients. The persistent background isn’t a static dark gradient: it’s a hand-written WebGL2 shader rendering a real blackbody-radiation heat-color progression across a glowing forged-steel surface, and every interactive tool on the site runs on real metal-forming engineering data.

1. A real forging heat-color chart. The genuine visual method forge operators use to judge steel temperature by eye — seven real stages from black through dull red, cherry red, orange, and yellow-white, each naming the forging operation appropriate at that heat, grounded in blackbody-radiation physics and standard forging references.

2. A real press-force / tonnage calculator. The standard flow-stress forging-force estimate F = k × Y × A (Kalpakjian & Schmid; ASM Handbook Vol. 14A) — pick a billet cross-section, a forging type (open-die vs. closed-die), and a material family, and see the real approximate required press tonnage, with an honest caveat about production-scale variables.

3. A real steel-grade mechanical properties comparator. Genuine published ASTM A36 / SAE J403-J404 AISI 1045/4130/4140/4340 yield strength, tensile strength, and elongation ranges in a toggleable comparator, not invented numbers.

The signature GPU background renders a glowing forged-steel surface from a hand-written WebGL2 fragment shader — a domain-warped height field driving both a real Blinn-Phong specular sheen and a real blackbody-radiation colour ramp, cold steel-blue at the top of the page warming through dull red, orange, and bright yellow-orange with visible heat shimmer and drifting sparks by the bottom. 12 demo forging/fabrication projects across 6 real service lines with real sourced industrial photography, every project entirely fictional — no real client, plant, or facility represented.
