If you’re carrying a knife in humid weather, wet conditions, or anywhere near saltwater, corrosion resistance isn’t optional—it’s essential. Some steels handle moisture without flinching, while others start spotting the second you forget to wipe them down. If you want a blade that’ll hold up without constant babying, it pays to know which steels can take the abuse. These seven options are known for staying clean, even when your gear gets grimy. They’re not magic, but they’ll save you from rust and pitting when it counts.
LC200N
LC200N is one of the most rust-resistant knife steels you’ll find, hands down. It was originally developed for aerospace parts exposed to saltwater, so it shrugs off moisture better than almost anything else. Even in wet or coastal conditions, it holds up without needing constant care.
The other surprise? It’s not just tough on rust—it’s actually pretty good at holding an edge, too. That balance makes it a solid option for everyday carry knives and anything you plan to take outdoors. It’s pricier, but it’s earned the hype.
H1 Steel
H1 doesn’t stain, doesn’t pit, and doesn’t care if you forget to wipe it down. It was made specifically for saltwater exposure, and it’s been a go-to for divers and fishermen for years. It basically trades edge retention for unbeatable corrosion resistance.
It’s a workhorse in wet conditions, even if you’re not near the coast. You’ll need to sharpen it more often, but the tradeoff is peace of mind. If you want a knife you don’t have to worry about, H1 is about as worry-free as it gets.
VG-10
VG-10 strikes a good balance between corrosion resistance and edge performance. It’s used in a lot of higher-end kitchen knives for a reason—it stays sharp, resists staining, and doesn’t flake out when exposed to water or food acids.
In pocket knives or fixed blades, VG-10 handles humid days and the occasional soak without much fuss. It’s not invincible, but with a little care, it’ll stay clean and sharp. For folks who want a well-rounded steel that holds up in real-world use, it’s a solid pick.
14C28N
14C28N was designed with corrosion resistance in mind, and it shows. It has enough chromium to fend off rust and enough carbon to keep an edge decently sharp. It’s a favorite for budget-friendly knives that still perform outdoors.
You’ll see this steel in a lot of hunting and fishing blades, and for good reason. It holds up when things get wet or dirty and sharpens up quickly if you ding it. If you’re on a budget but still want corrosion resistance, it punches above its price point.
Nitro-V
Nitro-V is a newer option that’s gaining traction because it actually does what it says. It resists rust well, especially for a steel that also has decent hardness and edge retention. It’s been used more often in custom knives, but more mainstream makers are starting to pick it up.
It handles moisture and field use better than some older stainless steels, and it won’t turn orange overnight if you forget to clean it. For EDC or camp knives, Nitro-V is worth keeping an eye on—it’s got staying power.
S30V
S30V isn’t the most rustproof on this list, but it’s still stainless and holds its own in most wet conditions. You won’t want to leave it soaking in saltwater, but with normal care, it stays clean and keeps a sharp edge longer than most corrosion-resistant steels.
It’s a good choice if you want something tougher than H1 or LC200N in terms of edge holding, but still need solid resistance to rust. It’s not a maintenance-free steel, but it’s proven itself in the field time and again.
N690
N690 is an underrated steel that’s popular in European knives. It resists corrosion better than most mid-range stainless steels and performs well in humid, wet environments. It’s often used in rescue knives and blades made for maritime use.
Edge retention is respectable, and it sharpens up nicely without being a pain. It’s a good alternative if you want something different from the usual VG-10 or 14C28N crowd. If you’re after reliable stainless performance, N690 is a name worth knowing.
