Resposta rápida
ASTM A193 Grade B6 is a heat-treated martensitic stainless-steel bolting grade associated with Type 410 aço inoxidável. It combines high strength with chromium-based oxidation and corrosion resistance for high-temperature or special-purpose joints specified by the design.
Visão geral do produto
O que são ASTM A193 Parafusos prisioneiros 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 ou 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, temperatura, galvanic couple, junta, nut grade and cleaning or passivation requirements must be reviewed together.

Por que especificar esta nota?
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.
Nota crítica de engenharia
B6 should not be selected solely because it is called stainless steel. Its corrosion resistance, dureza, tempering condition, stress-corrosion behaviour and compatibility with nuts and mating components must be verified for the actual environment.

Perguntas frequentes
What material is ASTM A193 B6?
B6 is a heat-treated martensitic stainless-steel bolting grade associated with Type 410 aço inoxidável.
Is B6 stainless steel magnetic?
Tipo 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 Nota 6 porcas sextavadas pesadas são comumente especificadas. Confirm nut properties, dimensões, finish and service compatibility in the purchase order.
Does B6 have the same corrosion resistance as 316 inoxidável?
Não. B6 and 316 have different alloy systems and corrosion behaviour. The process environment must be reviewed before selecting B6.
