Definitions

the invention relates to a high-strength low-alloy steel for seamless steel pipes with excellent weldability and resistance to stress corrosion cracking according to claim 1.
Seamless tubes made of high-strength steels are z. B. used for pipes for the transport of oil or gas, which are laid both onshore and offshore.
Alloys commonly used for seamless conduits are defined for steels up to 80 ksi (X80) in standards such as API 5L, DNV-OS-F101 and EN 10208.
these standards do not specify the limit values for the alloying elements.
it must be taken into account that the steel tubes produced from them are weldable and must possess good strength and toughness properties.
the strength-increasing mechanism which at the same time leads to an increase in toughness, is known to reduce the grain size. This can u. a. can be achieved by alloying nickel and molybdenum and the associated reduction in the transformation temperature.
Molybdenum additionally improves tempering resistance at higher tempering temperatures and through hardenability.
the addition of nickel deteriorates the surface quality of the hot-rolled tubes significantly from a certain alloy content.
micro-alloying elements such as titanium, niobium and vanadium are additionally used. Titanium precipitates at high temperatures, sometimes already in the liquid phase as a very coarse titanium nitride. Niobium forms niobium carbonitride precipitates at lower temperatures. With further decreasing temperature, vanadium additionally accumulates in carbonitrides, i. H. it is to be expected with the excretion of VC particles.
Coarse precipitates of these micro-alloying elements have a negative effect on toughness properties and acid gas resistance. Therefore, the content of these alloying elements should not be too high. Furthermore, the levels of carbon and nitrogen required for the formation of the precipitates must be taken into account.
a high strength low alloy steel for hot rolled seamless steel tubes that meets the requirements of an X100 API 5L for welded pipe is WHERE 2007/017161 A1 known.
This known steel alloy has an alloy concept with C: 0.03 - 0.13%, Mn: 0.90 - 1.80%, Si ⁇ 0.40%, P ⁇ 0.020%, S ⁇ 0.005%, Ni: 0.10 - 1.00%, Cr: 0.20-1.20%, Mo: 0.15-0.80%, Ca ⁇ 0.040%, V ⁇ 0.10%, Nb ⁇ 0.040%, Ti ⁇ 0.020%, N ⁇ 0.011% and a mixture of bainite and martensite.
this known steel has the mechanical properties and weldability required for a X100 (100 ksi) after a tempering treatment, its use as a gas pipe for H 2 S-loaded gas (sour gas) with regard to possible stress corrosion cracking is not stated , However, the chromium carbides possibly forming in the known steel may adversely affect acid gas resistance.
Ni contents are up to 1% in the known steel very high, resulting in the formation of adhesive scale on the surface during hot rolling of the tubes, for.
Rohrkontivon, etc. can affect and greatly affect the surface quality of the pipes and would require a complex machining finishing the surface required.
JP 6172855 A and WO 2004/031420 A describe other steel alloys that are also suitable for applications as a pipe.
Residual iron with melting impurities with optional addition of Ti and the proviso that the sum of the contents of Ti + Nb + V is a value of ⁇ 0.04 to ⁇ 0.15% and the ratio Cu / Ni a value of ⁇ 1 having.
the steel alloy according to the invention is based on the development of the pipe steels according to API 5L, ISO 3183, DNV-OS-F101 and EN 10208.
copper In addition to nickel, copper also has a positive effect on acid gas resistance.
the Ni content is max. 0.60% low enough to produce a sufficiently good surface quality for the tube manufacturing processes mainly used for this steel grade.
