X6Cr13 is a low-carbon chromium ferritic stainless steel containing about 13% chromium. This datasheet presents the material within the Werkstoff-Nummer (DIN / EN) designation system.
With about 13% chromium and low carbon, 1.4000 is the lower-carbon version of the 13% chromium martensitic grade and, unlike that grade, cannot be hardened by heat treatment. It shows resistance to steam, alkaline solutions, dilute acids (nitric, formic, oxalic), salts (nitrates, nitrites, carbonates) and hot petroleum fumes, fuels, alcohols, ethers, food products, lubricants, water and oils — adequate at low concentrations and low temperatures. Being ferritic and low-nickel, it is magnetic and offers good formability. It does not show resistance to intergranular corrosion before or after welding.
Typical applications include rectification (distillation) columns, cracking pipes, heat exchangers, machinery and food-industry equipment parts, and pressure-vessel linings.

| Environment | Performance | Notes |
|---|---|---|
| Atmospheric / general | Good | Adequate at low concentrations / temperatures |
| Steam / alkaline solutions | Good | Resists steam and dilute alkalis |
| Dilute acids (nitric, formic, oxalic) | Moderate | At low concentrations |
| Salts (nitrates, carbonates) | Moderate | At low concentrations |
| Intergranular corrosion | Not resistant | Before or after welding |
Corrosion resistance is adequate in mildly corrosive media at low concentrations and temperatures; the grade is not resistant to intergranular corrosion.
A low-carbon, non-hardening grade; cannot be hardened by heat treatment. Properties are set by annealing.
Anneal Heat to approximately 750–820 °C and cool slowly. The low-carbon composition avoids martensite formation. Avoid prolonged exposure near 475 °C (embrittlement).
Weldable; the low carbon limits heat-affected-zone hardening. However the grade is not resistant to intergranular corrosion after welding; use a stabilized or austenitic filler where corrosion resistance of the weld is critical.
| Welding Process | Applicability | Filler / Consumable |
|---|---|---|
| GTAW / TIG | Good | Matching or austenitic (309) for ductility |
| GMAW / MIG | Good | Matching or austenitic filler |
| SMAW / stick | Good | Matching or 309 electrode |
Austenitic fillers give a more ductile, corrosion-resistant weld where required.
Machining Guidelines
| Parameter | Recommendation |
|---|---|
| Machinability | Good; similar to other ferritic grades |
| Work hardening | Low rate — good formability |
| Coolant | Ample flood coolant |
Forming Processes
| Process | Notes |
|---|---|
| Cold forming | Good — bending, roll forming, drawing |
| Hot forming | ~1100–800 °C; anneal afterward |
| Industry | Typical Components | Key Requirements |
|---|---|---|
| Oil & coke | Rectification columns, cracking pipes | Steam / petroleum-fume resistance |
| Heat transfer | Heat exchangers | Mild corrosion resistance |
| Food industry | Machinery and equipment parts | Corrosion resistance + formability |
| Pressure vessels | Vessel linings | Corrosion resistance |
