ASTM A193 Grade B6 fully threaded Type 410 stainless stud bolts supplied with the required heat treatment, Abmessungen, matching nuts, surface condition and inspection records.
Schnelle Antwort
ASTM A193 Grade B6 is a heat-treated martensitic stainless-steel bolting grade associated with Type 410 Edelstahl. It combines high strength with chromium-based oxidation and corrosion resistance for high-temperature or special-purpose joints specified by the design.
Produkt auf einen Blick
Was sind ASTM A193 Stehbolzen B6?
ASTM A193 B6 stud bolts are manufactured from a hardened-and-tempered martensitic stainless grade associated with Type 410. Unlike austenitic grades such as 304 oder 316, B6 is magnetic and its heat treatment is central to obtaining the required mechanical properties.
The chromium content provides oxidation and moderate corrosion resistance, but B6 is not a universal substitute for 316 stainless or nickel alloy in aggressive media. The process fluid, Temperatur, galvanic couple, Dichtung, nut grade and cleaning or passivation requirements must be reviewed together.

Warum diese Note angeben??
Specify B6 when the approved design requires martensitic Type 410 stainless bolting for elevated-temperature strength, oxidation resistance or compatibility with the selected equipment material system.
Kritischer technischer Hinweis
B6 should not be selected solely because it is called stainless steel. Its corrosion resistance, Härte, tempering condition, stress-corrosion behaviour and compatibility with nuts and mating components must be verified for the actual environment.

Häufig gestellte Fragen
What material is ASTM A193 B6?
B6 is a heat-treated martensitic stainless-steel bolting grade associated with Type 410 Edelstahl.
Is B6 stainless steel magnetic?
Typ 410 martensitic stainless steel is normally magnetic. Magnetic response alone is not an acceptance test for ASTM A193 B6 compliance.
Which nuts match B6 stud bolts?
ASTM A194 Grad 6 Üblicherweise werden schwere Sechskantmuttern verwendet. Confirm nut properties, Abmessungen, finish and service compatibility in the purchase order.
Does B6 have the same corrosion resistance as 316 rostfrei?
NEIN. B6 and 316 have different alloy systems and corrosion behaviour. The process environment must be reviewed before selecting B6.
