SSMALLOYS B16.5 Flange Material Guide

SSMALLOYS provides a complete ASME B16.5 flange material cross reference system covering ASTM carbon steel, stainless steel, alloy steel, pipes, fittings, and fasteners for engineering applications.

Introduction | About SSMALLOYS Engineering System

In modern industrial piping systems, flange material selection is no longer an isolated decision.

A flange must be fully compatible with:

Pipa
Perlengkapan
Pengencang
Bars and plates

However, the widely used ASME B16.5 standard only defines:

Pressure classes
Ukuran
Facing types
Material groups

It does NOT provide a full system-level material compatibility map.

This is where SSMALLOYS Engineering Material System comes in.

SSMALLOYS Engineering Approach

At SSMALLOYS, we build materials not as isolated grades, but as:

🔩 Complete piping system solutions

Each material is evaluated as a full system package, including:

Flange material
Pipe material
Fitting material
Bolt and nut system
Raw material base (bars / plates)

All based on globally recognized standards from:

American Society for Testing and Materials
American Society of Mechanical Engineers

Each system includes:

✔ Flanges

ASTM A105 / A182 / A351 / A216

✔ Pipes

Seamless: ASTM A106 / A312 / A335
Welded: ASTM A53 / A671 / A312

✔ Fittings

ASTM A234 (Carbon & Alloy Steel)
ASTM A403 (Stainless Steel)

✔ Fasteners

ASTM A193 (Stud bolts)
ASTM A194 (Nuts)

✔ Raw Materials

ASTM A29 / A276 / A479 bars

Why SSMALLOYS Material System Matters

In real industrial projects, failures often come from:

Wrong material pairing
Incompatible pressure ratings
Mixed metallurgy systems
Incorrect fastener selection

SSMALLOYS eliminates these risks by ensuring:

🔒 Full system compatibility across all components
