904L stainless metal elbow

Item Description

Introduction

904L is a non-stabilised lower carbon large alloy austenitic stainless steel. The addition of copper to this quality gives it significantly improved resistance to robust lowering acids, specifically sulphuric acid. It is also extremely resistant to chloride attack – equally pitting / crevice corrosion and pressure corrosion cracking. This quality is non-magnetic in all conditions and has exceptional weldability and formability. The austenitic structure also provides this grade excellent toughness, even down to cryogenic temperatures. 904L does have quite significant contents of the high EPT components nickel and molybdenum. Numerous of the programs in which this grade has beforehand carried out properly can now be fulfilled at lower EPT by duplex stainless metal 2205 (S31803 or S32205), so it is employed considerably less commonly than in the past. Essential Houses These qualities are specified for flat rolled product (plate, sheet and coil) in ASTM B625. Similar but not always equivalent properties are specified for other items these kinds of as pipe, tube and bar in their respective specs.

Feasible Substitute Grades

EPTTble 5. Achievable substitute grades to 904L stainless steel.

Grade	Why it migEPTT be selected as an alternative of 904L
316L	A decrease EPT alternative, but with significantly reduce corrosion resistance.
6Mo	A greater resistance to pitting and crevice corrosion resistance is essential.
2205	A really comparable corrosion resistance, with the 2205 getting larger mechanical power, and at a reduce EPT to 904L. (2205 not appropriate for temperatures earlier mentioned three hundred degC.)
Super duplex	EPTer corrosion resistance is required, jointly with a higher energy than 904L.

Corrosion Resistance

Although initially deveXiHu (West EPT) Dis.Hu (West EPT) Dis.ed for its resistance to sulphuric acid it also has a really substantial resistance to a vast range of environments. A PRE of 35 suggests that the content has great resistance to heat sea drinking water and other higher chloride environments. EPT nickel content results in a much EPT resistance to stress corrosion cracking than the stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd austenitic grades. JCEP adds resistance to sulphuric and other reducing acids, notably in the really aggressive quotmid concentration quot range.

In most environments 904L has a corrosion efficiency intermediate among the stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd austenitic grade 316L and the extremely hugely alloyed six% molybdenum and equivalent quotsuper austenitic quot grades.

In intense nitric acid 904L has much less resistance than molybdenum-free grades these kinds of as 304L and 310L.

For maXiHu (West EPT) Dis.mum tension corrosion cracking resistance in critical environments the steel should be answer treated soon after cold function.

Heat Resistance

Good resistance to oXiHu (West EPT) Dis.dation, but like other hugely alloyed grades suffers from structural instability (precipitation of brittle phases such as sigma) at elevated temperatures. 904L need to not be employed previously mentioned about four hundred degC.

Heat Treatment

Resolution Treatment method (Annealing) – warmth to 1090-1175 degC and amazing swiftly. This quality can not be hardened by thermal therapy.

EPT

904L can be efficiently welded by all stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd methods. Treatment needs to be taken as this grade solidifies totally austenitic, so is susceptible to hot cracking, particularly in constrained weldments. No pre-warmth ought to be employed and in most instances post weld heat therapy is also not JCEP. AS 1554.6 pre-qualifies Quality 904L rods and electrodes for welding of 904L.

Fabrication

904L is a large EPT, low sulphur grade, and as this kind of will not EPTT effectively. In spite of this the grade can be EPTTd using stXiHu (West EPT) Dis.Hu (West EPT) Dis.rd strategies.

Bending to a little radius is readily carried out. In most circumstances this is done chilly. Subsequent annealing is EPTTly not JCEP, even though it must be regarded as if the fabrication is to be employed in an environment the place serious stress corrosion cracking problems are predicted.
